Wideband PRGW Polygon Antenna Augmented with Metamaterial Lens

Abstract

Gap waveguide is one of the promising technologies in 5G & mm-wave applications due to their low cost, low losses, and high power handling capability. In this work, we have proposed a featured design of an antenna with metamaterial layers to provide a high gain and wide bandwidth simultaneously. The antenna fed by an emerging guiding structure entitled Printed ridge gap waveguide (PRGW), which is planar, lower loss, and works very well at mm-wave frequency range. The antenna offers a stable radiation pattern with a very high gain of 12 dBi, which facilitates the utilization of such an antenna in covering large areas or achieving high penetration.
