    • Filter componentsbandpass filtering circuit of bandpass filter

      Electronic & Optoelectronics Innotech Expo Filter componentsbandpass filtering circuit of bandpass filter

      An equivalent LC model is developed to emulate the filter performanceto accelerate the design procedure. The source-load coupling renders this filter a cross-coupling effect which creates two transmission zeros by the passband edges for the signal selectivity enhancement.
    • Balanced bandpass filter design using the folded substrate integrated waveguide

      Electronic & Optoelectronics Innotech Expo Balanced bandpass filter design using the folded substrate integrated waveguide

      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.
    • Electromagnetic Engineering Surface

      Electronic & Optoelectronics Innotech Expo Electromagnetic Engineering Surface

      To solve the low transmission ratedisruption caused by the non-line of sightmulti-path transmission in indooroutdoor environment, a special electromagnetic surface is designed to guide the beam to the desired area with multiple reflections.
