Trace

Technical Name	Balanced bandpass filter design using the folded substrate integrated waveguide
Project Operator	National Changhua University of Education
Project Host	何明華
Summary	A novel balanced BPF using the folded half-mode substrate integrated waveguide has a central frequency of 4.65 GHz with 0.55 GHz BWin-band insertion loss of 2.2 dB. The size of an FHMSIW is about 1/4 of the substrate integrated waveguide (SIW). The common-mode rejection levels are greater than 40 dB over a wide frequency range.
Market Potential Analysis	需要無線通訊或是無線傳送與接收的場合越來越多，未來市場可期。
Industrial Applicability	The folded substrate integrated waveguide balanced BPF has advantages of EMC immunity property, wide BW, wide stopband, good CMRR,good signal selectivity. It can be used as a RF front-end filter component of a wireless communication system, such as wifiWLAN systems,cellar phone base station.
