Defected Top diamond shaped Patch Antenna for Multi-band operations

Abstract

A compact diamond-shaped antenna has been presented in this research work. This antenna has been designed to cover multiple technologies like WLAN, Wi-MAX, Bluetooth and applications included in S-band, C-band and X-Bands. The proposed antenna design has a diamond-shaped patch with half ground structure with notch and side cuts to achieve more efficient radiation patterns, and characteristic impedance is achieved. The presented antenna has dimensions 60×71.5×1.6 mm³, and the substrate is made of FR-4 material. The novel design and ground defections have achieved the proposed antenna’s wider operational impedance bandwidth of 9.954 GHz. In addition, its frequency bandwidth with VSWR<2 is from 1.294 GHz to 11.248 GHz, which covers multiple technologies like 5G networks, WLAN, Wi-MAX, Bluetooth, satellite and applications included in S-band, C-band and X-Bands or ultra-wideband (UWB). The optimized simulated geometry has a good match with the measured outcomes.
