Abstract

A historical 34-slot travelling wave, end-fire rectangular waveguide antenna that has not been previously qualified is examined using a commercially available software. Structurally, this antenna has some advantages over other travelling or leaky-wave antennas that could be used for 24GHz ISM band radar onboard a multirotor UAV, due to the all metal construction. The radiation pattern characteristics of the published antenna design were a peak directivity of 16.2dBi with 1dB directivity bandwidth of 12.2%.
