Design of PLUS-slot microstrip patch antenna for Bluetooth and Wi-MAX applications

摘要

Most of the devices are small in size and require small-size antennas. In this paper, we have investigated a unique design of microstrip antenna with three PLUS-slot of equal area. The geometry is such that three PLUS symbol at an angle of 0°, 45° and 90°. Simulation has been made using HFSS software. Results of proposed antenna proves it to be a good candidate for Bluetooth and WiMAX applications. Good bandwidth, uniform radiation pattern, VSWR value nearly equal to 1 gives excellent impedance matching and better gain of the antenna are achieved.
