Design and Implementation of Microstrip Antenna Hexagonal – Rectangular Patch 2x4 Array with H - Slot at 2.4 GHz Frequency

Abstract

Antenna microstrip is one of the lots of antennas used in system telecommunication specifically for microwave frequency. Antenna microstrip own a number of applications as in communication cellular and satellite, GPS, RFID, WiMax, radar, rectenna to use in the medical world. Antenna microstrip has weaknesses such as narrow bandwidth, small gain, and low efficient. In this article an antenna microstrip with hexagonal - rectangular patches 2x4 array will be designed without and with “H” slot. Antenna will be designed and simulated using CST 2019 software. Printing antenna using PCB with substrate made from epoxy fiberglass which has constant dielectric 4.58. Antenna’s parameters that will be measured are return loss, VSWR, gain, radiation pattern, and bandwidth. Measured parameter value then compared between antennas without slots and antennas that use slots with hope antenna microstrip with slots capable of expands bandwidth from antenna without slots. The testing result show that return loss of antenna microstrip without slot is -10.1 dB with bandwidth of 9.45 MHz and return loss of antenna microstrip with a slot is -11.73 dB with bandwidth of 55.59 MHz so can concluded that bandwidth of antenna slots is 46.14 MHz bigger than antenna microstrip without slots.
