摘要

我们展示了一种新型的带通滤波器，它由工作在低语廊模式下的介电谐振器和一对光子带隙结构微带线构成。光子带隙结构用于抑制预定传输峰周围的杂散模式。该滤波器的中心频率为13.7 GHz, Q值为2.000，插入损耗为7 dB，杂散模抑制为30 dB。

High-Q whispering gallery mode resonator filter with photonic bandgap spurious mode suppression

We demonstrate a novel bandpass filter constructed with a dielectric resonator operating in a whispering-gallery mode and a pair of photonic bandgap structured microstrip lines. The photonic bandgap structure is used to suppress the spurious modes around an intended transmission peak. The fabricated filter has a center frequency of 13.7 GHz, a Q of 2.000, an insertion loss of 7 dB and a spurious-mode suppression of 30 dB.
