A Dual-Polarized Horn Antenna for mm Wave Applications

A dual-polarized horn antenna based on 4 cavity slots is proposed. The total height of the antenna is 27 mm. The antenna is matched for VSWR = 2 between 25.8 to 29.8 GHz (14.4%) and the port-to-port isolation is between -46 dB to –55 dB in this range. The directivity of the antenna at 28 GHz is 15.6 dBi and the total efficiency is -0.8 dB. The E-plane beamwidth is 37 degrees with sidelobes at -17.4 dB and cross-polarization level lower than –70 dB. The H-plane beamwidth is 20 degrees with sidelobes lower than -21 dB and cross-polarization level lower than -65 dB.
