To accurately detect objects, the radar antenna must have a high gain for the desired range. The antenna uses an array method to increase the gain. It has a unidirectional radiation pattern to meet the X-band radar implementation as a ship navigation tool. The X-band radar works at high frequencies. Thus, it will be more sensitive in detecting small particles, including rain particles. The use of a mitered-bends feeding network method by cutting the 90-degree curve is to maximize the power transmitted to reduce losses. This method spreads the bandwidth of the antenna. The antenna is designed and fabricated into a linear array of 8 elements, using the R04003C Rogers substrate with a microstrip line supply. This study limits up to 8 elements of radiation, followed by the addition of a method to expand the bandwidth of antennas. Considering material limitation and duration of antenna design. The final antenna dimensions are 142.40 mm × 42.8 mm. The measuring results show fc = 9.496 GHz, S11 = -32.64 dB, VSWR 1.05, bandwidth = 41.9 MHz (9.5159 GHz - 9.4740 GHz), and gain 8.8 dB as well as a linear polarized antenna with unidirectional pattern direction. The radar antenna tends to have a narrow beamwidth and high gain.

Abstrak -Radar maritim merupakan sistem yang menggunakan gelombang radio frequency (RF) yang digunakan untuk mengetahui keberadaan suatu objek, kecepatan dan jarak dari objek. Salah satu subsistem pada radar adalah antena. Antena pada radar digunakan untuk memancarkan dan menerima gelombang elektromagnetik. Antena memiliki berbagai jenis, salah satunya adalah antena mikrostrip. Antena mikrostrip banyak digunakan karena ukurannya yang kecil dan ringan, mampu beroperasi pada frekuensi yang tinggi serta memiliki pola radiasi yang terarah. Antena yang dirancang pada penelitian ini adalah antena mikrostip patch segiempat linier array 1×4 dengan pencatuan inset pada frekuensi 3,2 GHz dengan lebar pita 60 MHz dan gain ≥ 10 dB. Pada perancangan antena menggunakan substrat Epoxy Fiberglass-FR 4 dengan ketebalan 1,6 mm dan konstanta dielektrik 4,3. Untuk proses simulasi antena menggunakan perangkat lunak AWR Microwave Office. Dari hasil penelitian antena mampu bekerja pada frekuensi 3,2 GHz, hasil simulasi nilai VSWR 1. Hasil simulasi antena MPSPI linier array 1×4 pada frekuensi 3,2 GHz diperoleh VSWR = 3,17 dan 3,23 Ghz dan return loss -11,85 dB, dengan dimensi masing-masing patch-nya sebesar 31x22 mm.dengan impedansi 51,6 Ω dan gain 14,39 dB. Kata Kunci: Antena Mikrostrip, Linier array 1×4, Radar maritimAbstrak -Maritime radar is a system that uses radio frequency (RF) waves which are used to determine the whereabouts of an object, the speed and distance of the object. One of the subsystems on the radar is the antenna. The antenna on the radar is used to transmit and receive electromagnetic waves. Antennas have various types, one of which is a microstrip antenna. Microstrip antennas are widely used because of their small size and light weight, capable of operating at high frequencies and having a directional radiation pattern. The antenna designed in this study is a 1×4 linear quadrilateral microstrip patch antenna with an inset feeder at a frequency of 3.2 GHz with a bandwidth of 60 MHz and a gain of ≥ 10 dB. In the design of the antenna using Epoxy Fiberglass-FR 4 substrate with a thickness of 1.6 mm and a dielectric constant of 4.3. For antenna simulation process using AWR Microwave Office software. From the results of research on the antenna being able to work at a frequency of 3.2 GHz, the simulation results of the VSWR value are 1. The simulation results of the 1×4 linear array MPSPI antenna at a frequency of 3.2 GHz obtained VSWR = 3.17 and 3.23 Ghz and return loss -11 .85 dB, with the dimensions of each patch of 31x22 mm. with an impedance of 51.6 Ω and a gain of 14.39 dB.
