A Series-fed High-Gain Gap Waveguide Planar Array Antenna Fed by Quasi-TEM Wave
Paper i proceeding, 2020

A series-fed high-gain gap waveguide planar array antenna is presented in this paper. The element is a corporate-fed long slot pair which is series-fed by the quasi-TEM wave in the oversized rectangular gap waveguide. Using the methods of the quasi-TEM wave and series-fed concept, the proposed array antenna achieves a simple structure, low profile and high gain. The proposed array antenna is designed based on the gap waveguide technology, which makes it possible to simplify the assembly and fabrication tolerances. The simulated results show that the impedance bandwidth with the reflection coefficient below -10 dB is covering 34.54-35.41 GHz. The antenna achieves a maximum gain of 31.7 dBi and high efficiency of 87.1% at 35 GHz.
