Abstract

Short range radar (SRR) uses the K-band frequency range in its application. The radar requires high-resolution, so the applied frequency is 1 GHz wide. The filter is one of the devices used to ensure only a predetermined frequency is received by the radar system. This device must have a wide operating bandwidth to meet the specification of the radar. In this paper, a band pass filter (BPF) is proposed. It is designed and fabricated on RO4003C substrate using the substrate integrated waveguide (SIW) technique, results in a wide bandwidth at the K-band frequency that centered at 24 GHz. Besides the bandwidth analysis, the analysis of the insertion loss, the return loss, and the dimension are also reported. The simulated results of the bandpass filter are: VSWR of 1.0308, a return loss of -36.9344 dB, and an insertion loss of -0.6695 dB. The measurement results show that the design obtains a VSWR of 2.067, a return loss of -8.136 dB, and an insertion loss of -4.316  dB. While, it is obtained that the bandwidth is reduced by about 50% compared with the simulation. The result differences between simulation and measurement are mainly due to the imperfect fabrication process.

Abstract

Directional coupler frekuensi radio (RF) menggunakan dua jalur mikrostrip asimetris dibahas dan dirancang dengan struktur planar pada substrat duroid 5880. Directional coupler yang diusulkan terdiri dari dua jalur mikrostrip dengan jarak yang relatif dekat. Oleh karena itu, sinyal RF dapat ditransfer dari satu jalur mikrostrip ke jalur mikrostrip lain. Directional coupler telah dianalisis untuk frekuensi yang beroperasi pada daerah X-band dengan menggunakan perangkat lunak Advance Design Systems (ADS) dan berhasil dipabrikasi menggunakan proses pabrikasi standar. Dalam pengukuran divais ini, diperoleh koefisien coupling sekitar 20 dB untuk frekuensi operasional 9,2 sampai 9,9 GHz. Hasil pengukuran mempunyai suatu kesepakatan dengan hasil perhitungan. Berdasarkan hal tersebut, maka directional coupler dapat digunakan untuk sistem radar X-band.
