Low Cost Microwave Radar Modules For 3, 10, and 24 GHz This example page showcases 3D EIRP radiation patterns for three popular consumer/hobbyist radar modules. All three are normally used for proximity sensing and intruder detection. The physical size of all three antennas is nearly constant, but their “electrical size” (in terms of wavelength) increases […]
Example 15: Quad Ridge Dual Polarized Vivaldi Horn
This sample report features a dual polarized Vivaldi antenna, evaluated with our 3D polar patterns at standard resolution (10 degree steps). The antenna was swept from 1300 MHz to 18 GHz. Background: This interesting eBay antenna find is a pair Teflon PCBs. It was specified in its listing as 698 to 6000 MHz for mobile […]
Example 2: Polar Plots of WA5VJB Mini LPDA
Inexpensive Broadband Antenna This sample report features a compact broadband antenna, evaluated with our 2D polar patterns at high resolution (1 degree steps). The antenna was swept from 700 MHz to 18.5 GHz in 251 steps. The PCB log periodic dipole array (LPDA) antenna used for this report was designed by Kent Britain WA5VJB and […]
Antennas By RFSpace
We love these low cost practical antennas by RFSPACE. They offer a range of interesting planar Vivaldi, LPDA, and horn antennas that are broadband and directional at reasonable prices. Their product line is being extended to some narrow-band and omni-directional broadband antennas as well. The Vivaldi Antenna (sometimes called a Tapered Slot or Vivaldi Notch) […]
