PERBANDINGAN ANTENA MIKROSTRIP ARRAY DUAL BAND DENGAN PENCATUAN MICROSTRIP LINE DAN ELECTROMAGNETICALLY COUPLED (EMC)

Single microstrip antenna has the characteristics of narrow bandwidth and small gain. This paper discusses the design of a microstrip array antenna that works at two working frequencies, namely 2.4 GHz and 5 GHz for WiFi. The method used to obtain dual band frequencies is by adding slots on the side of the patch. The results obtained are the 4-element microstrip array antenna with feed line supply has better results when applied to WiFi. This feed line antenna has a bandwidth of 75 MHz - 184.4 MHz in accordance with IEEE 802.11n standards and has a gain of 4.321 dBi. Whereas the EMC supply has a large gain of 11.54 dBi but the bandwidth obtained is very narrow, namely 27.5 MHz.
