Design of A Wideband Array Antenna Prototype with Gap Waveguide for W-Band Wireless Links

Paper i proceeding, 2018

This paper presents a wideband 45o slot array
antenna for W-Band wireless links. The proposed antenna
prototype consists of 44 slot array, a wideband T-junction
based on a groove gap waveguide and a vertical transition
from WR-10 to groove gap waveguide. The simulated results
show that the proposed prototype has an impedance bandwidth
of 26.5% with input reflection coefficient better than
-10 dB.
