Sectorial antenna based on vertical microstrip elements

An 120 degrees sectorial antenna uniformly-fed array, based on vertical microstrip elements is discussed. The bandwidth of the antenna is 16% for VSWR = 2 around 4 GHz. Two configurations are discussed: (A) An array with gain of 12.3 dBi, sidelobe level of -13.9 dB and elevation beamwidth of 12 degrees, (B) An array with 11.2 dBi gain, sidelobe level of -17… (More)
