Study on the Performance of Novel Planar Dual-mode Microstrip Bandpass Filter
A novel planar dual-mode elliptic-function microstrip bandpass filter with two triangle corner cuts and a square notch is proposed, and the performance of the designed filter is studied in detail. The proposed filter structure uses a single patch without coupling gaps. The center frequency is about 2.13GHZ. The 3dB fractional bandwidth is 9.86％, and the minimum insertion loss in the passband is 0.13dB.There are two transmission zeros on both sides of the passband. The insertion loss is < idB and return loss is > lOdB within 2.08-2.22GHz. The effect on the filters performance by changing filter parameters is studied. The results show that this new filter can provide a low insertion loss and reduce uncertainty in fabrication. It also makes miniaturization easy.
