Analisis Pengaruh T-Shaped Slot terhadap Kualitas Parameter Antena Mikrostrip menggunakan Computer Simulation Technology (CST) dan Advanced Design System (ADS) untuk Aplikasi Wi-Fi

Abstract

Microstrip antenna is widely used because it has several advantages such as  small dimension and light weight. However, this antenna also has weaknesses, which are limited bandwidth and low gain. Therefore, this antenna is designed for the purpose of obtaining a wide bandwidth. This research is to design and simulate a microstrip patch antenna rectangular T- shaped slot to support wi-fi communication and using stripline as a transmission line. An antenna designed for the purpose of obtaining a wide bandwidth, is expected to produce the characteristics of antennas working at a resonant frequency of 2447 MHz for VSWR less than 2 with the type of substrate used is FR4 Epoxy with a relative permittivity value is 4.4, dielectric constanta is 2,2, and the thickness is 1,6, also impedance of transmission line is 50 ? that operate in frequency resonant 2,447 GHz. According to design and simulation this antenna, value of bandwidth impedance is about 103 MHz for VSWR 1,367, gain about 5,337 dB, and directivity about 6,238 dBi. And the result of simulation on ADS simulator, the value of VSWR is 2,083, with gain about 0,505 dB, and directivity about 6,063 dBi.
