TL;DR: In this article, a reconfigurable wideband and multiband C-slot patch antenna with dual-patch elements is proposed and studied, where two parallel C-Slots on the patch elements are employed to perturb the surface current paths for excitation of the dual-band and wideband modes.

TL;DR: In this article, a patch antenna is presented which has been designed to radiate frequencies in the range 4-9.5 GHz into human breast tissue and is shown by means of previously unpublished simulation and practical measurements to possess a wide input bandwidth, radiation patterns that remain largely consistent over the band of interest and a good front-to-back ratio.

TL;DR: A breast cancer detection technique using multi-static radar, using backscatter data produced from an anatomically realistic 2D MRI-derived FDTD model of the breast is proposed, although clarity of detection is dependent on mitigating antenna mutual coupling and skin reflections.

TL;DR: A novel transparent ultra-wideband antenna for photovoltaic solar-panel integration and RF energy harvesting, designed and fabricated to provide UWB communications whilst integrated onto solar panels as well as harvest electromagnetic waves from free space and convert them into electrical energy.

TL;DR: In this article, a small ultra-thin printed inverted-F antenna (PIFA) with independent control on the resonant frequency bands is proposed and optimized to operate at 2.09, 3.74 and 5 GHz with achievable bandwidths of 11, 8.84% and 10%, respectively.
