Abstract

Sistem radar banyak digunakan dalam perkembangan teknologi telekomunikasi. Radar dapat dimanfaatkan untuk mendeteksi lokasi, navigasi kendaraan dan juga informasi cuaca. Dalam sistem radar, digunakan antena mikrostrip array yang dapat mempersempit beamwidth sehingga target yang dideteksi lebih akurat. Di dalam antena mikrostrip array terdapat power combiner/divider yang berfungsi untuk menggabungkan daya pada port input dan membagi daya pada port input menjadi beberapa port output. Parameter yang perlu diperhatikan pada power combiner/divider adalah dimensi, return loss dan insertion loss yang dibuat serendah mungkin.
Dalam penelitian ini, akan direalisasikan power combiner/divider yang bekerja pada frekuensi S band yang akan dimanfaatkan untuk sistem coastal radar. Power combiner/divider ini akan dirancang menggunakan metode SIW (Substrate Integrated Waveguide) dan HMSIW (Half Mode Substrate Integrated Waveguide). Dari metode tersebut, diharapkan dapat merancang power combiner/divider 1 to 4 yang memiliki 1 port input dan 4 port output. Tujuan rancangan tersebut adalah untuk mengefektifkan dan mengefisiensikan pemakaian power combiner/divider pada sistem radar tersebut.
Hasil akhir dari penelitian ini menghasilkan power divider 1 to 4 yang memiliki rentang frekuensi kerja 2,19-2,84 GHz dan 3,07-3,86 GHz dengan fractional bandwidth 48,6%. Power divider juga menghasilkan nilai return loss dibawah -10 dB, nilai insertion loss diatas -10 dB dengan toleransi 1 dB dan power eqality -9,9 ± 0,88 dB. Power divider bekerja paling optimum pada frekuensi 2,6 GHz.

Radar systems are widely used in the development of telecommunication technology. Radar can be used to detect location, vehicle navigation and weather information. In a radar system, a microstrip array antenna is used which can narrow the beamwidth so that the detected target is more accurate. In the microstrip array antenna there is a power combiner/divider that used to combine power on the input port and divide the power into several output ports. Parameters that need to be considered in power combiner/divider are dimension, return loss and insertion loss which are made as low as possible.
In this study, a power combiner/divider will be realized that works in the S band frequency which will be used for the coastal radar system. The power combiner/divider will be designed using the SIW (Substrate Integrated Waveguide) and HMSIW (Half Mode Substrate Integrated Waveguide) methods. From those methods, it is expected to be able to design a 1 to 4 power combiner/divider that has 1 input port and 4 ouput ports. The aim of the design is to make the usage of power combiner/divider effective and efficient on the radar system.
The result of this study is to produce a 1 to 4 power divider which has a working frequency range of 2.19-2.84 GHz and 3.07-3.86 GHz with fractional bandwidth 48.6%. The power divider also produces return loss value below -10 dB, insertion loss value above -10 dB with a tolerance 1 dB and power equality -9.9 ± 0.88 dB. The power divider works best at frequency 2.6 GHz
