A printed Quasi-Yagi Antenna with a new feed, Substrate Integrated Coaxial Line (SICL) working in the millimeter wave frequency range is presented. This new feeding technique makes the antenna design simple, surpasses the need to have balun and reflector. The antenna design presented here operates at 28GHz with a frequency band of 6.8 GHz, providing a gain of 7.2dBi and front to back ratio of better than 9dB. The SICL section exhibits good shielding ability which is advantageous for circuits implemented in millimeter wave frequency range. It also enhances the performance of the antenna by providing a shielding to feed network. It also reduces the complexity of the feeding network and makes it compact. This antenna is suited for millimeter wave automotive radar application operating at K Band (18-26 GHz). © 2018 IEEE.
