Compact and High Performance Bandpass Filter Based on an Improved Hybrid Resonator Using Beeline Compact Microstrip Resonator Cell (BCMRC)
In this paper, a compact microstrip bandpass filter is presented by using a proposed improved hybrid resonator. Without requiring the cross-coupling and the source-load coupling, the new filter has a transmission zero on the upper stopband to provide a high selectivity. The fabricated filter is desi...

Summary: | In this paper, a compact microstrip bandpass filter is presented by using a proposed improved hybrid resonator. Without requiring the cross-coupling and the source-load coupling, the new filter has a transmission zero on the upper stopband to provide a high selectivity. The fabricated
filter is designed at f
0
= 1 GHz and has a compact size of 0.112λ

. Good agreement is observed between the measurements and simulations. The measured results show that the new filter has a wide −60 dB rejection upper
stopband from 1.24f
0
to 4.05f

. In addition, a −20 dB rejection ultra-wide upper stopband is measured from 1.08f

to 15.38f

. The new filter can be fabricated using the standard printed-circuit-board (PCB) process
and has a planar topology, which is easily integrated with the modern wireless communication system. |
