Design and simulation of copper and carbon nanotube rectangular patch (single and array) antenna

Abstract

In this paper, we designed a rectangular patch single and array antenna by using CST software version 18.0. First, we used a copper as radiating patch and then the nanomaterial conductor like carbon nanotube (CNT) to improve the antenna performance. In both cases, the operating frequency is 2.4 GHz, which is used for many communication applications including Wi-Fi and Bluetooth. We have designed the four-element patch array antenna in two forms of arrangement (series and corporate feed). We used the substrate FR4 (its height=1.6 mm, Єr=4.3) and copper as the ground in all our designs. The return loss (s parameter) Always less than 10 dB the value of voltage standing wave ratio (VSWR) was close to the one in the designs. The highest directivity obtained from a patch array (1×4) antenna was 13.5 dBi when using carbon nanotube. Finally, we made a comparison of the analyzed results after simulation in a detailed table of the basic antenna properties, Including Return loss, VSWR, gain and directivity at the resonant frequency.
