A K-band Biconical Antennas System for Wireless Wideband Communication


Abstract — In this paper a biconical antennas system operating in a wideband TX/RX video and voice communications module is described. The antenna module is part of a K-band (38.3-38.6 GHz) equipment installed in a vehicle on the move composed by two different units: the IDU, indoor unit, is installed inside the vehicle and the ODU, outdoor unit, is installed on the top of the vehicle. The ODU is composed by the RF transceiver and the antennas system that is formed by two equal biconical antennas performing the transmitting (TX) and receiving (RX) functionality respectively. The fabricated antennas, characterized by reduced size and low weight, are feeded through WR28 rectangular waveguide obtaining minimum insertion loss in connecting the antennas itself with the system
