TL;DR: In this paper, a low-profile substrate integrated waveguide (SIW) cavity-backed slot antenna is presented, where two hybrid modes, whose dominant fields are located in different half parts of the SIW cavity are two different combinations of the and resonances.

TL;DR: In this paper, a three-dimensional (3D) structure for ultra-wideband absorber design is proposed, which is implemented by properly combining two subabsorbers, and their simulated fractional bandwidths of 151.6% and 150.9% are achieved, respectively.

TL;DR: Low profile cavity backed antennas (CBA) based on substrate integrated waveguide (SIW) technology presented in published papers have been reviewed in this article, where operating mechanisms have been discussed and methods for improving the performance, such as bandwidth enhancement, size reduction, and gain improvement, have been presented.

TL;DR: In this paper, a dual-mode substrate-integrated waveguide (SIW) bandpass filters exploiting perturbed SIW rectangular cavities are proposed, where the resonant frequency of TE101 mode can be shifted close to that of TE201 mode, thus creating a dualmode resonator.

TL;DR: An improved dynamic hierarchical clustering method is adopted and two strategies that include a double cluster head (CH) strategy to reduce the load of a cluster head in a large cluster, and a node dormancy mechanism to balance the energy consumption of the network are implemented.
