LRAD Microstrip Antenna Array

Typical measured LRAD co-pol and cross-pol array antenna patterns are shown on a separate page. These patterns were measured at the GAAMS facility, NASA GSFC. At 1.413 GHz the -3 dB beamwidth was 11.5 degrees, the antenna gain was 20.9 dBi, with a -25 dB sidelobe level. Cross-pol level was -37 dB. Insertion loss was 2.5 dB.
