Paper title: A FREQUENCY SELECTIVE SURFACE LOADED HIGH GAIN SLANT ANTENNA FOR 2.45 GHZ RECTENNA APPLICATIONS

Author(s): UDAYABHASKAR PATTAPU, SUSHRUT DAS,

Abstract:

This paper presents a 2.45 GHz ground slot backed harmonic rejection slant antenna for wireless power transfer applications. The harmonic responses have been suppressed by using two stubs and a U-shaped ground slot. The antenna provides 3.1 dBi gain at 2.45 GHz. To improve the gain, a 2.45 GHz reflective frequency selective surface has been placed below the ground plane at an optimized distance of 0.12 λ0. After placing the FSS, antenna gain has been increased to 7.57 dBi without affecting the return loss characteristic. The antenna has been fabricated and the simulation results are experimentally verified.
