Abstract

UWB (Ultra Wide Band) merupakan teknologi yang digolongkan sebagai Short Wireless Range (SWR) yang memiliki pita frekuensi 3,1 GHz – 10,6 GHz, menduduki beberapa frekuensi kerja sistem komunikasi radio lainnya, yaitu sistem WiMAX (Worldwide Interoperability for Microwave) frekuensi 3,3 GHz dan sistem WLAN (Wireless Lokal Area Network) frekuensi 5 GHz. Hal ini menyebabkan adanya potensi interferensi antara ketiga sistem tersebut. Untuk menjaga perangkat UWB, maka dibutuhan bandstop filter yang mampu menghasilkan dua buah respon stopband sekaligus untuk menstop frekuensi WiMAX dan WLAN. Dual Band Bandstop Filter (DBBSF) merupakan salah satu teknologi filter mikrostrip yang dapat menekan sinyal yang tidak diinginkan secara efektif bersamaan di dua frekuensi terpisah. Pada penelitian ini dibahas perancangan sebuah dual band bandstop filter mikrostrip dengan metode defected structure dual plane, desain model T-DMS (Defected Microstrip Structure) pada top plane untuk menghasilkan daerah kerja frekuensi stopband pertama 3,3 GHz – 3,4 GHz dengan bandwidth 100 MHz dan desain model U-DGS (Defected Ground Structure) pada bottom plane untuk menghasilkan frekuensi stopband kedua 5,150 GHz – 5,825 GHz dengan bandwidth 675 MHz. Filter disimulasikan dengan menggunakan software CST Microwave Studio 2014, kemudian dilakukan fabrikasi dan pengukuran untuk memverifikasi hasil rancangan filter. Pengukuran menggunakan Vector Network Analyzer R3770. Hasil pengukuran filter tanpa casing diperoleh frekuensi kerja stopband pertama 3,484 GHz dengan bandwidth 285 MHz, insertion loss -35dB, return loss -2,2dB, VSWR 7 dan frekuensi stopband kedua 5,403 GHz dengan bandwidth 519 MHz, insertion loss -46dB, return loss -2,2dB, VSWR 7. Dan Hasil pengukuran filter dengan menggunakan casing diperoleh frekuensi kerja stopband pertama 3,521 GHz dengan bandwidth 266 MHz, insertion loss -46dB, return loss -2,7dB, VSWR 6 dan frekuensi stopband kedua 5,478 GHz dengan bandwidth 569 MHz, insertion loss -35dB return loss -1,3dB, VSWR 12. UWB (Ultra Wide Band) is a technology that is classed as Short Wireless Range (SWR) has frequency bands 3.1 GHz– 10.6 GHz, occupying some of the frequencies of other radio communication systems work, that is WiMAX system (Worldwide Interoperability for Microwave) frequencies of 3.3 GHz and WLAN system (Wireless Local Area Network) a frequency of 5 GHz. This led to the existence of potential interference between the three systems. To keep UWB devices, then become bandstop filter that is able to produce two response stopband at once to stop frequency WiMAX and WLAN. Dual Band Bandstop Filter (DBBSF) is one of the microstrip filter technology that can suppress unwanted signals effectively simultaneously in two separate frequencies. On this research discussed the design of a dual-band bandstop filter with mikrostrip method defected structure dual plane, the design of the model T-DMS (Defected Microstrip Structure) on the top panel to generate a working area first stopband frequency 3.3 GHz – 3.4 GHz with a bandwidth of 100 MHz and design models U-DGS (Defected Ground Structure) on the bottom plane to produce a second 5.150 stopband frequency GHz – 5.825 GHz with a bandwidth of 675 MHz. Filter is simulated by using software CST Microwave Studio 2014 , and then do the fabrication and measurement to verify the results of the design of the filter. The measurement using Vector Network Analyzer R3770. The results of measurements of the filter without casing retrieved working the frequency of the first stopband 3.484 GHz with a bandwidth of 285 MHz insertion loss -35dB, return loss -2,2dB, VSWR 7. And the frequency of the second stopband 5.403 GHz with a bandwidth of 519 MHz, insertion loss -46dB, return loss -2,2dB, VSWR 7. And measuring results using the filter casing retrieved working the frequency of the first stopband 3.521 GHz with a bandwidth of 266 MHz, insertion loss -46dB, return loss -2,7dB, VSWR 6. and the frequency of the second stopband 5.478 GHz with a bandwidth of 569 MHz insertion loss - 35dB, return loss -1,3dB, VSWR 12.
