| Abstract: | A new kind of open/ shorted-ended T-shape stub-loaded ring resonator is put forward. Through the theoretical analysis based on odd-even mode theory and the calculation based on electromagnetic simulation software, a dual-band band-pass filter is designed. The center frequency is 0. 4 GHz (P-band) and 1. 2 GHz (L-band), and the fraction bandwidth is 40% and 16.26% respectively. The advantage of this filter is low insertion loss, small volume and easy integration. It is suggested that this dual-band band-pass filter and its design could be widely applied to the high integrated network of the radar antenna array system. |
