Abstract :
In this paper we present the design of a millimeter-wave antenna based on recently developed ridge gap waveguide (RWG) technology. This is the first antenna designed based on this technology to operate in V-band (45-70 GHz). The antenna operates at 68.7 GHz with a bandwidth of 900 MHz. The feed network consists of a quarter-wavelength ridge gap waveguide resonator that excites a slot in the top metal plate. The corners of the slot are optimized for improved impedance matching. The simulated antenna has a gain of 7.0 dBi and an input reflection coefficient of -20.8 dB. Finite-element based electromagnetic simulations show that it is possible to scale ridge gap waveguide designs to operate in V-band.
