A New Method of Isolation Enhancement of Dual Band Band-Pass Filter Using Composite Mode Co-planar Waveguide Structure for 5G and Body Centric Applications

Frequency ratio or frequency difference of more than fifteen times between the two bands is difficult to realize particularly for millimetre-wave applications. This paper presents a large dual band band-pass filter 5G communication and body-centric The proposed has been studied developed based on mode-composite co-planar waveguide (MC-CPW). comprises lower higher designed independently with high degree freedom. In order suppress harmonics bands, lowpass cascaded structure impedance matching achieve competent response. characteristics mode composite yield it as promising potential entrant multi-band operating systems in To certify practicability pre-eminence filter, simulated measured results are compared found good agreement one another.
