Optimalisasi Antena Mikrostrip Tiga Pita Untuk Penerapan Pada WLAN dan WiMAX

Wired WLAN (Wireless Local Area Network) technology emerged as the most widely used network. is suitable for those who need internet. By using will be found various advantages its users. Likewise with WiMAX (Worldwide Interoperability Microwave Access) wireless technology, basically has a function similar to WLAN, but certain small differences. can cover one local area, in contrast which metropolitan area of ​​up 50km. Antenna an integral part and WiMAX. This paper discusses three-band microstrip antenna optimized WIMAX technology. The consists two layers FR4 (epoxy) printed circuit board (PCB) thickness (h) 1.6 mm, dielectric constant (εr) 4.4, loss factor (tan) 0.02 dimensions 35 mm × 48 . simulated CST software. design Studio Suite 2018 done by adjusting size slot spacing, length slot, ground clearance, length. In this design, increased on left side patch increase pitch deeper return loss, right shorter loss. results simulation process obtained good working frequency, bandwidth operate at expected frequencies, namely 2.4 GHz, 3.2 5.1 GHz -42 dB, -44 - 31 dB. Bandwidths 114.4 MHz, 121.2MHz 287.9MHz.
