TL;DR: A multiband antenna for mobile phone applications operating in GSM, DCS, PCS, UMTS, Bluetooth, and LTE bands is presented and ways in which the ring can be modified so as to restore the desired performance of the antenna are investigated.

TL;DR: In this article, a checkerboard metasurface based on a novel physical mechanism, optimized multielement phase cancellation, is proposed for greatly expanding the bandwidth of radar cross section (RCS) reduction.

TL;DR: In this paper, a dual-polarization frequency-selective rasorber (FSR) with two absorptive bands at both sides of a passband is presented, and the positions and values of resistors are determined according to the analysis of modal significances and modal current.

TL;DR: In this article, an absorptive/transmissive frequency selective surface (ATFSS) with wide absorption bands at both sides of a passband was presented, where a double-layer structure consisting of a lossy FSS and a lossless FSS was employed.

TL;DR: Based on polarization conversion and destructive interference, a novel monolayered metasurface is proposed for ultrawideband monostatic and bistatic radar cross section (RCS) reductions for both copolarization and cross polarization as discussed by the authors.
