Reduced sized dual frequency microstrip antenna

Abstract

A novel, compact, single probe-feed square microstrip patch antenna for operation in dual frequency can be achieved by cutting unequal finger like rectangular slots perpendicular to the radiating edges. From the experimental results obtained, the proposed antenna is about 67% smaller compared to a traditional rectangular patch operating at the same frequency and we have got the dual frequency operation in two different bands i.e. L and S bands.

Impact of Patch and Slot Antenna

“…Due to the advancement of technology microstrip patch antennas are used in modern printed circuit technology, MMIC design, GPS communication system, Wireless Local Area Network (WLAN), Synthetic Aperture Radar (SAR). Considerable effort has been devoted to the development and improvement of the bandwidth, return loss and reduction of size [3][4][5][6][7][8][9][10][11].…”

Study and Analysis on Compactness of Patch Antenna Utilizing Ground Plane with U Slot

“…Very usual process of getting compact antenna is to increase the electrical path length so that resonant frequency is decreased. To increase the current route on the patch, numerous slots have been sliced into the radiating patch in this technique [1][2][3]. The modification on the ground plane also keeps the effect on lowering the resonant frequency.…”

Effects of Two Identical Notches in the Same and Opposite Non Radiating Edges of a Rectangular Microstrip Patch Antenna

“…Many researchers have used different techniques to design compact microstrip patch antenna. S. Bhunia et al, [3][4] has investigated on compactness and multi frequency operation of microstrip patch antenna cutting rectangular slots on the patch and almost 85% size reduction is reported. Size reduction by slot loading in the radiating patch of the microstrip patch antenna has also been reported in the literature [5 -7].…”
