Abstract

In this paper, a Fabry-Perot cavity antenna with an improved gain using AMC-reflector and FSS superstrate approaches is proposed. The antenna is designed at 5.8 GHz for IoT applications, it constitutes of I-shaped slot antenna, an artificial magnetic conductor (AMC) reflector and a superstrate of frequency selective surfaces (FSS). Three antenna configurations are provided to improve the gain and reduce the side lobe levels (SLL). First, an I-shaped slot antenna operates at 5.8 GHz, is proposed. The second configuration provide an AMC reflector layer, placed under the antenna, to degrade SLL in the desired band. Finally, three FSS superstrate layers located above the I-shaped slot antenna in order to maximize the level of the main lobe. An experimental prototype is fabricated, tested and presented to demonstrate the proposed antenna design. Simulated and experimental results, in terms of reflection coefficient, radiation pattern and gain, are presented and discussed to assess the proposed antenna design.
