✦ Synopsis

In this article, the design and realization of waveguide filter with improved stop-band response is presented. By inserting transversal slots at the proper position of cavities, without disturbing the field distribution of the dominant mode, the second longitudinal resonant modes are radiated out. This caused the out-of-band frequency response of the filter to be improved. The validity of the proposed technique is confirmed by comparison between measurement values and simulation results from the finite element method through the commercial software (high frequency structure simulator). Also, to assure electromagnetic compatibility the slot surfaces are covered by absorbing material. V

## Abstract This letter proposes a parallel coupled‐line bandpass filter (BPF) using the folded slotted ground structures (SGSs) to improve the wide stopband. It is shown that the designed folded SGS has a very small area in comparison of previous works. The folded SGS exhibits a dual stopband char

In this article, a new method is suggested to improve the frequency responses of dual-mode waveguide filters employing cross-shaped slots. According to this method, regarding one cross-shaped slot between two cavities, the horizontal (vertical) mode in one cavity influences the vertical (horizontal)
