Microstrip antenna design for UWB applications using finite ground plane approach

This paper reports the design of a Microstrip patch antenna for the first band of Ultra Wide Band (UWB) frequency range of 3.1–3.6 GHz. As the bandwidth requirement is around 500MHz, finite ground plane approach has been incorporated in the antenna design. The designed antenna provides a gain of 5.9dB which is observed to be a better compared to the conventional antennas designed for the specified frequency range. The maximum directivity achieved is 6.16dB and the radiation efficiency obtained is about 80%. The designed antenna is well suited for indoor applications where high data rate and quick transmission are important requirements.
