A novel design of triple-band cross slotted antenna for WLAN and WiMAX applications

The research paper employs a triple-band cross-slotted antenna which is developed and constituted on FR4 substrate with an elongation of the microstrip feed line for WLAN and WiMAX Applications. The patch resonates at S and C bands by inserting a cross-slot on a patch as well as on a ground plane. The conventional microstrip antenna undergoes huge in size, narrow impedance bandwidth, max r eturn loss, lowest radiation efficiency, and poor VSWR. The novelty of this research work be enough rich for possible choice to configure the tiniest antenna with enhanced bandwidth, minutest return loss, escalated radiation efficiency, and intensified VSWR. Initially, the antenna is resonating in double-band without alteration but after placing slots on the patch and the ground plane, it resonates at triple-band of 3.17 GHz, 5.76 GHz, and 7.02 GHz with the highest bandwidth of 2.1 GHz, lowest return loss of - 65.0326 dB, the best VSWR of 0.0097, and upgraded efficiency of 1.2983. This antenna detects applications of weather radar, surface ship radar, some satellite communication, WLAN (2-4 GHz), and long-distance communication, WiMAX (4-8 GHz).
