Narrow Channel Multiple Frequency Microstrip Antenna with Slits

Abstract

In this paper, a narrow channel multiple frequency microstrip patch antenna is proposed. This paper entrusts the trend for not using wider channels, which is even though an increasing trend now a days, but instead we advocate that the radio communication should take place over multiple channels for fair and efficient spectrum utilization. For this purpose, we present a narrow channel multiple frequency rectangular microstrip patch antenna having slits. The proposed design is applicable for commercial frequency bands of 3.20, 5.5, 6.25, and 7.96 GHz which makes it useful for the modern wireless communication purposes (2–8 GHz). HFSS version 13.0 is used for design, evaluation, and analysis of the proposed antenna design. The design is analyzed for radiation pattern, return loss, VSWR, and gain, where the simulated results infer that the planned antenna design shows appreciable performance in terms of VSWR, gain, return loss, and radiation pattern at resonant frequencies.
