Gain Enhancement of Membrane Antenna Utilizing Dielectric Lens for Millimeter Wave Applications

Abstract

The design, configuration and simulation results of a membrane antenna integrated with homogenous hemispherical dielectric (Teflon) lens is presented. The membrane antenna consists of six layers and a homogenous extended hemispherical dielectric lens, which is placed over the top layer of membrane antenna. The longitudinal rectangular slot etched in the SIW ground plane is utilized to excite the micros trip patch antenna (MPA). The membrane antenna gain is enhanced by integration of a homogenous extended hemispherical dielectric lens. The proposed antenna operates in millimeter wave band and having bandwidth of 6 GHz (90 - 96 GHz). Furthermore, the antenna gain is found to be above 15 dB.
