Abstract

Pada penelitian ini dirancang sebuah microstrip passive phase shifter berbentuk meander coupled- line yang dapat di implementasikan untuk menggeser fasa sejauh 90⁰ sehingga dapat memudahkan dalam sistem pengarahan antena. Antena dirancang di atas substrat FR-4 dengan nilai permitivitas relatif 4.6 pada frekuensi S-Band (3 GHz), yaitu frekuensi yang digunakan pada Airport Surveillance Radar yang berfungsi untuk memantau pergerakan pesawat saat masuk, keluar atau hanya melintasi wilayah bandara tertentu. Metode yang digunakan adalah Schiffman’s phase shifter sebagai acuan perancangan. Pada jurnal ini, direalisasikan microstrip passive phase shifter dengan return loss untuk sebesar -14.7 dB dan pada        sebesar -14.6 dB. Sedangkan nilai fasanya senilai 97.22⁰ untuk           dan 92.56⁰ untuk      .

Abstract

A Bluetooth was developed as a means for short-range communications. However, the limited range of Bluetooth devices that tend to be narrowly led to the use of Bluetooth is less developed. Whereas, with its properties, sharing of data should be done easily and cheaply. This research has designed a transceiver antenna for Bluetooth communications that works at a frequency 2.4 GHz ISM-band. The antenna is designed in the form of a microstrip antenna with Complementary Split Ring Resonator (CSRR) methods to reduce the dimensions of the antenna. The result of this research is a form of a transceiver antenna that works at a frequency of 2.398 GHz to 2.47 GHz with -30.815 dB return loss and VSWR worth 1,074. The resulting radiation pattern is a directional pattern with a gain of 11.84 dB. Implementation of the CSRR method can reduce antenna dimension by 53.47 %.
