Filtering Power Divider menggunakan Filter SIW untuk Aplikasi WLAN 5,8 GHz

In this paper power divider integrated with filtering process, named as Filtering Power Divider (FPD), is developed to achieve a compact size of the device. The proposed FPD is composed of 2 pieces of Band Pass Filter (BPF) designed based on Substrate Integrated Waveguide (SIW) to operate at the Wireless Local Area Network (WLAN) frequency of 5.8 GHz. The optimizations are carried out using a simulation software to investigate the effect of different filter parameters to the filtering process as well as to the output response of FPD. A Duroid 5880 dielectric substrate with the thickness of 1.575 mm is used to realized the FPD with the total dimensions of 95 mm x 70 mm. The realized FPD has a bandwidth response of 75 MHz in the frequency range of 5.9 GHz to 5.975 GHz and isolation between output ports is 20 dB.
