Triangular UWB antenna with reduced ground plane effect

Abstract

This article gives brief view of UWB microstrip antenna characteristic without a slot and with a triangular slot on the patch of the MSA. Nowadays UWB antenna is a must for wireless communication with the narrow pulses in the series of nanoseconds, for the application of ultra-wideband in frequency domain for very short distance and minimum power densities. The research in this field has become more sought-after and therefore the demand on UWB microstrip antenna is rising rapidly. The currents along the verge of the slot initiates additional resonance, it concords with the main patch resonance, which result in the production of overall frequency response characteristics, ultimately leads to wideband. Thus a crisp novel ultra-wideband configuration with and without a triangular slot have been proposed. And the radiation is in the broadside of antenna with small variation along the entire bandwidth. Thus improving the robustness of the MSA and cost reduction. Due to the potential of UWB antennas,they are significant to improve the performance of wireless communication systems. The MSA (microstrip antenna) is designed with FR-4 substrate. There is increase in bandwidth due to the introduction of triangular slot in the patch and the variation in the antenna parameters are briefed below. This document can be used as guide to design small MSA for mobile communication.
