TL;DR: In this paper, a miniaturized single-feed multiband patch antennas are proposed for wireless communication. But the antenna size reduction is achieved by loading shorting metalized vias on one edge of the radiating patch, while multiband is obtained by etching inverted multiple U-shapes.

TL;DR: In this paper, a miniaturized design of a four-element dual-band MIMO antenna system was proposed, where the edge-to-edge elements spacing is only 0.41λ0 × 0.023 λ0.

TL;DR: In this article, a substrate integrated waveguide (SIW) diplexer using the dual-mode resonator is presented, where the cavity can be employed as the common resonator to replace the T-junction.

TL;DR: In this paper, a compact $E$ -plane waveguide filter using multiple resonators, which lead to multiple transmission zeroes, is presented. But the proposed method is to design the locations of transmission zero locations, and the couplings between the resonators and locations of the transmission zero are carefully analyzed and designed to enhance the selectivity as well as the out-of-band performance.

TL;DR: In this paper, two U-shapes are etched on the same platform to locate the radiating patches which are excited separately using two feed ports, and metalized vias acting like metal walls are applied to reduce the antenna footprint, and to avoid coupling effects when the frequency ratio (fr ) approaches 2.
