Aperiodic Isophoric Slotted Waveguide Antenna for Point-to-Point Communications at Ka-band
Paper in proceedings, 2017

We report the intermediate results on a novel slotted waveguide antenna for point-to-point communications at Ka band. The antenna adopts an aperiodic layout with uniformly excited elements capable of meeting the ETSI class II radiation pattern envelop in all planes with high aperture efficiency. A total of 16 regular waveguide subarrays with an aperiodic inter-column spacing along the E-plane are fed by a corporate feed network located underneath. The prototype was milled in three layers of aluminum and bonded by vacuum brazing. Measurements confirm a 15% impedance bandwidth. The simulated patterns satisfy the radiation pattern envelop and have a gain above 28.5 dBi over 29-31 GHz, corresponding to an efficiency better than 80%.
