Abstract

The present paper deals with design and realization of the metasurface-reflector, high-gain directional ultra-wideband (UWB) bowtie antenna for the applications of IoT and wireless communication. There will be a modified patch along with a symmetrical hexagonal-shaped metasurface (MTS) reflector that has a design 3 × 6 array and is loaded on the back and top sides. First, the proposed design features an ultra-wideband bowtie antenna with a superellipse-shaped bow along with staircase structures. Then, the antenna becomes directional due to the metasurface loading on its backside, after that placing same metasurface on the front side enhances the directional gain. The dimension of the antenna is

2.44 λ_{0} \times 1.12 λ_{0}

and the fractional bandwidth is 97.44%. The maximum gain achieved by the antenna is 10.1 dBi, and the efficiency of the proposed antenna is 95.5%. This proposed compact antenna optimizes both gain and bandwidth for the requirements of IoT, UWB wireless operation, and 6G complementary networks.
