In the last decade, the filter community has innovated both design techniques and the
technology used for practical implementation. In design, the philosophy has become “if you …

RF/microwave bandpass filters (BPFs) are fundamental components in high-frequency RF
transceivers. On the transmitter side, they limit the transmitted RF signal bandwidth by …

This brief reports on the electromagnetic (EM) design and the practical development of
frequency-reconfigurable quasi-reflectionless bandpass filters (BPFs) using substrate …

This letter reports on the RF design and practical development of miniaturized substrate-
integrated-(SI)-coaxialresonator-based bandstop filters (BSFs). Size compactness is …

In this paper, a miniaturized wideband bandpass filter in coaxial substrate integrated
waveguide (SIW) technology is presented. To improve the response selectivity and coupling …

A novel type of a highly integrated low-loss stack-up is explored that leverages additive
manufacturing for the integration of a 3D printed and metal-coated air-filled waveguide with …

This paper presents a novel technique for low-cost realization of fully additively
manufactured passive microwave components through Stereolithography and selective …

A technique for designing bandpass filters with very flat amplitude response is presented in
this paper. The approach is based on the use of non-uniform-Q resonators implemented in …

A compact ultra-wideband bandpass filter employing substrate integrated quasi-lumped
resonators is presented in this paper. A multi-layer hybrid structure is proposed, combining …

In today's crowded RF spectrum, receivers must be highly selective to mitigate any
interference, whether intentional or from adjacent channels. The upper part of the C band (4 …
