Abstract
A three sections circular waveguide aperture antenna with conical beam is presented. By using two waveguide steps, the aperture distribution of the antenna can be controlled to realize the requirements on the radiation pattern with conical beam including the flare angle, gain and the side lobe level. Through optimized design, the impedance bandwidth of 550MHz with -10 dB return loss, the gain of 8.1 dB and a flare angle of 50 degrees have been achieved at the central frequency 35 GHz. Good agreement has been observed between simulated results and measured ones. The proposed antenna is easy to be fabricated and suitable for many applications.
