Bandwidth Enhanced Microstrip Patch Antenna for UWB Applications
Subscribe/Renew Journal
The main aim is to design a compact microstrip patch antenna with bandwidth enhancement for UWB applications by introducing L-Shaped patch with a U-slot. The microstrip patch antenna are having compact profile, simple structure and easy for fabrication. The main disadvantage lies with this is narrow bandwidth. In this paper, an Inverted L-Shaped patch is designed on the top of the substrate and a U-Slot is etched in the infinite ground plane and it is found to be achieving bandwidth enhancement of up to 28% with a compact size of 24×36mm2. This structure operates at the frequency of 5.2GHz and 7.4GHz for UWB applications. The performance of the fabricated prototype has also been compared and validated.
