Development of a miniaturized CPW-fed rectangular microstrip patch antenna with l and s shaped strips for WLAN, WiMAX and IMT applications

Abstract

In this paper, a pioneering CPW-fed compact rectangular microstrip patch antenna having L and S shaped meander strips has been propounded for WLAN, WiMAX and IMT applications. The antenna design has been simulated, fabricated as well as theoretically analysed by transmission and cavity model for setting up a correlation between the frequencies, thus helping in anticipating the frequencies to be calculated on paper. The proposed antenna resonates well below -10 dB covering the required bandwidth of 2.7/3.4/4.4 GHz IMT, 5.1 GHz WLAN and 3.4/5.2 GHz WiMAX standards. A close agreement was obtained while comparing the measured radiation pattern and gain results for the proposed antenna with the simulated ones.
