Low Profile Corrugated Horn for Minimum Side lobe Levels based on PRGW

Advances in wireless and satellite communications have created a demand for high-power microwave and millimeter-wave components due to cost, loss, and manufacturing complexity considerations. One of the newest and most promising guiding technologies is the Gap Waveguide, which is expected to have an effective role in mmWave and submmWave applications, not only in 5G communications but also in other future communications. In this article, we propose a corrugated grooved bow tie antenna based on PRGW to enhance the side lobe level in E and H planes. The antenna is operating from 32-36 GHz with a −10 dB matching level. The obtained side lobe level is in the range of −15 dB in both planes with 10 dB gain over the whole band of operation.
