Abstract
Ultra wideband (UWB) merupakan teknologi yang dipublikasikan oleh
U.S Federal Communication Commission (FCC) yang disetujui termasuk
unlicensed frequency. Teknologi ini mempunyai low EIRP level sebesar (-
41.3dBm/MHz), komsumsi daya yang rendah yaitu hanya 100 mW, mendukung
resolusi yang tinggi terhadap suatu objek, dan memiliki keakuratan dalam orde
milimeter. Beberapa keunggulan UWB tersebut sangat sesuai dalam
pengaplikasian Ground Penetrating Radar (GPR) yang merupakan suatu perangkat
yang digunakan untuk mendeteksi objek di bawah permukaan tanah menggunakan
gelombang radio.
Penelitian ini menawarkan desain bandpassfilter yang compact dapat
bekerja pada rentang 2-2,5 GHz atau memilki fractional bandwidth >20% sesuai
dengan spesifikasi FCC GPR UWB pada rentang mid frequency. Pada
perancangan filter UWB, filter direalisasikan dengan menggunakan teknologi
Half mode Substrate Integrated Waveguide (HMSIW) dengan dual mode.
Pemilihan teknologi SIW dikarenakan memiliki beberapa keunggulan dibanding
dengan waveguide konvensional yaitu pada ukuran yang lebih kecil, cost yang
lebih minim dan lost yang rendah.
Dalam analisis simulasi, filter yang dirancang memiliki nilai cut-off pada -
3 dB yaitu 2 GHz dan 2.5 GHz untuk lower dan higher cut-off frequency
Selanjutnya pada filter fabrikasi dilakukan analisis pengukuran. Analisis
menunjukkan bahwa UWB-BPF yang difabrikasi memiliki nilai cut-off yaitu 1.93
GHz dan 2.55 GHz untuk lower dan higher cut-off frequency.
============================================================
Ultra wideband is published by the US Federal Communication
Commission (FCC) approved including unlicensed frequency. This technology
has low level of EIRP (-41.3dBm / MHz), low power consumption (100 mW),
support high resolution, and accurate for millimeter orde. Some advantages of
UWB is very appropriate in application of Ground Penetrating Radar (GPR),
which is a device used to detect objects below ground level using radio waves.
This study offers a compact design bandpassfilter is from 2-2.5 GHz or
has a fractional bandwidth > 20% that satifies FCC UWB GPR specifications at
mid frequency. In the design of UWB filter, the filter is realized by using the
technology Half Mode Substrate Integrated Waveguide (HMSIW) with a dual
mode. SIW technology selection due to have several advantages compared with
conventional waveguide is compact, low-cost and also has a low loss
characteristic.
By simulation analysis, the designed filter has -3dB cut-off of 2 GHz and
2.5 GHz for lower and higher cut-off frequency, respectively. Furthermore, the
fabricated UWB-BPF is examined through measurement analysis. The
measurement analysis shows that the fabricated UWB-BPF has cut-off of 1.93
GHz and 2.55 GHz for lower and higher cut-off frequency .
