This paper presents a single-element microstrip spade-shaped patch antennas with partial ground plane, integrated an electromagnetic band-gap (EBG) structure, and fed feedline to achieve wideband, dual-band band-notched characteristic. Two similar mushroom-like EBG structures built into the wideband antenna were used suppress specific band, resulting in dual-band. The wide-band achieved broad b...

In this paper, a dual-band RF wireless power transfer (WPT) system with shared-aperture Tx array antenna for 2.4 and 5.8 GHz is proposed. The final configuration of the array, which made up right-handed circular polarization (RHCP) patches RHCP patches, derived from optimization thinned arrays, ultimately to achieve high transmission efficiency various WPT scenarios. including module implemente...

We report a dual-band-swept, Fourier domain mode locking (FDML) laser with sweeping rate of 97.6 kHz. The laser uses a custom-designed dual-channel driver to achieve synchronization between two tunable filters. It is the first time to achieve simultaneous dual-band FDML laser. © 2012 Optical Society of America OCIS codes: (300.6360)Spectroscopy, laser; (140.4050) Mode-locked lasers

Novel microstrip dual-band bandpass filters with controllable fractional bandwidths and good in-between isolation are presented and implemented. A half-wavelength stepped-impedance resonator is firstly characterized, aiming at producing the two resonant frequencies at 2.4 and 5.2 GHz. Two types of coupled microstrip lines in the parallel and anti-parallel formats are then investigated in terms ...
