摘要：

In this article, a novel E-plane substrate inserted waveguide bandpass filter with high selectivity and compact size is proposed in Ka-band. By integrating an extra resonator between two metal septa, the E-plane waveguide filter is achieved with two transmission zeros at both sides of the passband which contribute to the high-skirt selectivity. One sample is fabricated, whose total length is just 5 mm, namely, less than 0.5 lambda g and the minimum insertion loss is only about 0.3 dB. Good agreements between simulated and measured results are obtained. (C) 2013 Wiley Periodicals, Inc.
