Abstract

Penelitian ini bertujuan untuk analisis teknik 4 layer parasitic dengan pencatuan proximity coupling pada aplikasi antena radar cuaca pada frekuensi 5,6 GHz. Penelitian dilaksanakan di Laboratorium Telekomunikasi Fakultas Teknik Universitas Negeri Jakarta pada Juni sampai Desember 2022. Penelitian menggunakan metode Research and Development (RnD) melalui 5 tahapan yakni penentuan spesifikasi antena radar cuaca, penentuan dimensi antena konvensional dan antena menggunakan teknik 4 layer parasitic dengan teknik proximity coupling, perancangan dan simulasi menggunakan perangkat lunak CST Studio Suite 2019. Bahan yang digunakan adalah FR-4 yang memiliki konstanta dielektrik (ε_r ) sebesar 4,3. Hasil uji simulasi pada antena konvensional yang disusun sebanyak 16 elemen memiliki dimensi 470 mm×50 mm dengan return loss 18,64 dB, VSWR 1,26, bandwidth 254 MHz, gain 8,733 dB dan beamwidth 5.8°, sedangkan antena dengan 4 layer parasitic menggunakan pencatuan proximity coupling yang disusun sebanyak 16 elemen memiliki dimensi 470 mm×50 mm dengan return loss 14,49 dB, VSWR 1,46, bandwidth 1.033 MHz, gain 12,20 dB dan beamwidth 5.4°. Penambahan 4 layer parasitic berhasil meningkatkan performansi antena mikrostrip pada parameter gain. Teknik air gap pada penambahan 4 layer parasitic dapat menurukan nilai effective dielectric constant pada antena karena mempengaruhi nilai efisiensi yang juga berpengaruh terhadap nilai gain. **** This study aims to analyze the parasitic 4 layer technique by recording proximity coupling in the application of weather radar antennas at a frequency of 5.6 GHz. Research was carried out at the Telecommunications Laboratory of the Faculty of Engineering, Universitas Negeri Jakarta from June to December 2022. The research used the Research and Development (RnD) method through 5 stages, namely determining the specifications of weather radar antennas, determining the dimensions of conventional antennas and antennas using 4 layer multilayer techniques with proximity coupling techniques, designing and simulating using CST Studio Suite 2019 software. The material used is FR-4 which has a dielectric constant (ε_r ) of 4.3. The simulation test results on conventional antennas arranged as many as 16 elements have dimensions of 470 mm×50 mm with return loss 18,64 dB, VSWR 1,26, bandwidth 254 MHz, gain 8,733 dB and beamwidth 5.8°, while antennas with parasitic 4 layer using proximity coupling incapacitation which are arranged as many as 16 elements have dimensions of 470 mm×50 mm with return loss 14,49 dB, VSWR 1,46, bandwidth 1.033 MHz, gain 12,20 dB and beamwidth 5.4°. The addition of a parasitic 4 layer successfully improves the performance of the microstrip antenna in the gain parameter. The air gap technique in the addition of parasitic 4 layers can reduce the effective dielectric constant value on the antenna because it affects the efficiency value which also affects the gain value.
