Antenna Engineering Consulting Services: RF, Microwave and mmWave Antenna Design
SiberSci, LLC designs, simulates, builds and measures antennas from 1 MHz to 300 GHz. Projects are led by Founder & CTO Dr. Scott Best, Ph.D. (University of Utah, 1996), an IEEE Life Senior Member with three U.S. patents. SiberSci develops new antennas and fixes existing ones that miss their gain, pattern, bandwidth or VSWR targets. Past work includes the 24-element octagonal patch array shown here, 76–81 GHz radar arrays and a lung-tumor ablation antenna laboratory.
Antenna problems SiberSci solves:
- VSWR above 2:1 (return loss worse than 9.5 dB) across the required band
- Gain, pattern or resonance that shifts once the antenna is inside its enclosure (antenna detuning)
- Phased-array pointing error or sidelobes above the limit (array calibration case study)
- Ablation antennas that must control the heating pattern in tissue (microwave ablation system design)
- A new antenna that must fit a fixed size, weight or cost budget

Antenna Applications by Frequency
| Application | Frequency | Free-space wavelength | Typical antenna |
|---|---|---|---|
| HF RFID (near field) | 13.56 MHz | 22.1 m | Loop coil, much smaller than a wavelength |
| UHF RFID (far field) | 902–928 MHz (U.S.) | 33.2–32.3 cm | Dipole or patch tag and reader antennas |
| Microwave ablation | 915 MHz or 2.45 GHz | 32.8 cm or 12.2 cm (much shorter in tissue) | Coaxial interstitial antenna |
| X-band arrays | 8–12 GHz | 3.75–2.50 cm | Patch elements and phased arrays |
| Automotive radar | 76–81 GHz | 3.94–3.70 mm | Planar millimeter-wave arrays |
Wavelength λ = c / f, with c = 299,792,458 m/s. Try your own frequency in the SiberSci Wavelength Calculator.
Quick check: a half-wave dipole at 915 MHz is λ/2 = 16.4 cm in free space. A thin wire dipole resonates when it is about 5% shorter, roughly 15.5 cm. Put it near plastic, a PCB or a hand and it detunes again, which is why SiberSci simulates the antenna inside its real enclosure and then measures it.

What Antenna Engineering Consulting Covers
Most antenna projects start in one of two ways: a new product needs an antenna that does not exist yet, or an existing antenna stopped meeting its specification once it was built, packaged or installed. SiberSci, LLC handles both. For a new design, SiberSci weighs the electrical requirements (frequency, bandwidth, gain, pattern, polarization and VSWR) against size, weight, environment and cost, and identifies one or more antenna configurations that can meet them. For an existing antenna, SiberSci measures it, models it and isolates the cause before recommending changes. Antenna types SiberSci has designed, grouped by family:
- Reflectors: parabolic, corner, Cassegrain and inverse Cassegrain
- Horns: standard gain and corrugated
- Lenses: dielectric, Luneburg and Rotman
- Wire: monopole, dipole and helix
- Planar: patch and spiral
- RFID: HF near-field and UHF far-field
- Medical: tissue ablation
- Arrays: beamforming networks for software-defined radios
- Custom: application-specific designs
The list above is not complete. If your geometry is not on it, send the requirements anyway. Every design review ends with a written record of what each candidate can and cannot do. If part of a specification breaks a physical limit, such as a gain target that needs a larger aperture than the size budget allows (gain rises with aperture area divided by λ²), SiberSci flags the conflict before hardware is built and proposes the closest workable trade: a larger aperture, a narrower band, a different feed or a different antenna family. From there, SiberSci can carry the chosen design through prototyping, measurement, optimization and transfer to manufacturing.

Antenna Simulation Tools and Material Data
For computational electromagnetics (CEM), SiberSci uses Ansys HFSS, CST Microwave Studio, FEKO and COMSOL for full-wave work, plus Sonnet, Keysight ADS and Keysight Genesys for planar circuits. The 3D solvers handle antennas inside enclosures and on vehicles; the planar tools handle printed feeds and matching networks. If you hold a license or will cover contract access, you can name the tool; otherwise SiberSci recommends one.
A simulation is only as accurate as its material data. Permittivity, loss tangent and conductivity change with frequency and temperature, so SiberSci uses values measured in the lab or by a contract lab rather than catalog numbers, and compares each model against lab measurements of the hardware.

Antenna Engineering FAQ
FAQ
What Antenna Engineering consulting services does SiberSci, LLC provide?
SiberSci, LLC provides antenna engineering consulting for RF, microwave, and millimeter-wave applications, covering research, design, development, prototyping, and optimization of new antennas, as well as performance improvement of existing antennas. Projects are led by Dr. Scott Best and use both analytical and numerical (computational) electromagnetic methods.
What types of antennas can SiberSci design?
SiberSci designs wire, reflector, planar, conformal, lens, ablation, and sensing antennas. Specific designs include patch antennas, phased and patch antenna arrays, parabolic and corner reflectors, Cassegrain and inverse Cassegrain reflectors, standard gain and corrugated horns, dielectric, Luneburg, and Rotman lenses, spiral antennas, near-field and far-field RFID antennas, and application-specific antennas.
Can SiberSci improve an antenna I already have instead of designing a new one?
Yes. SiberSci optimizes existing antennas that are not meeting requirements, for example poor impedance match (VSWR or return loss), insufficient gain or bandwidth, an unwanted radiation pattern, or performance that degrades once the antenna is installed in an enclosure or system. Improving an existing design is often faster and less costly than starting over.
What frequency ranges does SiberSci work in?
SiberSci works across the RF, microwave, and millimeter-wave bands. Because SiberSci also provides RF, microwave, and millimeter-wave circuit engineering, antenna work can include the surrounding hardware such as feed networks, transmission lines, impedance matching networks, baluns, couplers, and waveguide components.
Who is the antenna engineer behind SiberSci?
SiberSci, LLC was founded by Dr. Scott Best, an electromagnetic engineer with experience in both industry and government. SiberSci is listed in the IEEE-USA Consultants Database and is a BBB Accredited Business based in Owensboro, Kentucky.
How does SiberSci protect my intellectual property?
SiberSci provides a Non-Disclosure Agreement (NDA) that the client can review, negotiate, and amend before any sensitive details are shared. The NDA protects business-sensitive information, intellectual property (IP), and proprietary data (PD). When you first make contact, state whether an NDA is required.
How much does antenna engineering consulting cost?
Cost depends on the scope of the project. After reviewing your antenna's performance and size requirements, SiberSci provides a budgetary quotation and a schedule. Work begins once a contract has been negotiated and signed by both parties.
What information should I include when requesting an antenna design quote?
Include the operating frequency and bandwidth, required gain and radiation pattern, polarization, impedance and VSWR targets, size, weight, and mounting constraints, the operating environment, the target quantity or cost, and your schedule. A clear description of the work to be performed lets SiberSci return an accurate budgetary quotation faster.
What is an ablation antenna?
An ablation antenna delivers concentrated RF or microwave energy into a material or tissue to heat it in a controlled way. In medicine, microwave ablation antennas are used to destroy tumors and other tissue. Designing one requires careful control of the heating pattern and impedance match inside a lossy medium, which is a specialty SiberSci supports alongside its RF and microwave heating work.
Does SiberSci provide expert witness or patent services for antenna technology?
Yes. SiberSci provides expert witness services and electromagnetic patent review and preparation for antennas and other RF, microwave, and millimeter-wave devices, circuits, subassemblies, and systems.
Does SiberSci offer free antenna design tools?
Yes. SiberSci offers free online electromagnetic calculators, including a Wavelength Calculator that can be used to size a monopole antenna, a Skin Depth Calculator for choosing conductor thickness, and waveguide and coaxial transmission line calculators.
