Super wide-band slotted trishul-shaped microstrip patch antenna for wireless applications

Abstract

In this article, a Trishul-shaped or rotated E-shaped microstrip patch antenna (MPA) rotated by 270 degrees is proposed. Two rectangular slots have been etched both from the top and bottom of the rectangular radiator to give it the shape of rotated E and inset-cut feed line respectively. The strip of copper is used as a ground plane which is behaving as a parasitic element in this case. The overall antenna size is 30.9 X 25.7 mm2 designed on FR4 substrate. Computer Simulation Technology Microwave Studio Version (CST MWS) tool is used to design and simulate the proposed antenna structure. The antenna has an extremely wideband coverage of 15.401GHz (1.61 to 17 GHz). Consequently, this antenna has an advantage of covering a wide range of wireless applications. The antenna is further fabricated and tested to check for the close approximation of simulated and measured results.
