PATCH ANTENNAS

We are able to identify critical issues such as the board layout, ground plane size, mounting methods and port measurement that influence the efficiency of your antenna. We’ll look at the polarization and radiation patterns, gain, impedance matching and frequency tolerance to determine the ideal patch for your design. With our computer modeling abilities, we can quickly determine your best options. In addition, we have an on-site anechoic chamber to validate performance. Our flexible manufacturing and testing processes allow us to easily accommodate your custom specifications. Features include:

  • Spectrum Microwave offers optimized designs for peak performance
  • These passive devices offer typical gain response from 0 dBi to 3 dBi for half-power bandwidths of 110°
  • Gain at boresite (90° elevation) can exceed 6 dBi depending upon the proper selection of a ground plane

  • Antenna radiation patterns provide excellent gain across all elevation angles but can also be manipulated for more focused requirements
  • The antennas not only transmit and receive circularly polarized signals but also linearly polarized signals
  • Antennas can be tuned and optimized very easily making prototyping quick and cost effective

  • Antennas designed with higher dielectric values are typically < 8 mm in height
  • Depending on your bandwidth requirement, they can be as low as 4 mm
  • Dimensions for antennas from 1 GHz to 6 GHz are from 13 mm to 50 mm square (excluding the ground plane)
  • These small antennas can be worn on a person with little notice
