A dual-band single-layer single-feed dual-band U-slot antenna, with linear polarization and single/dual-beam radiation pattern, is proposed for WLAN [2.40-2.4835 GHz and 5.15-5.35 GHz (indoor)] systems. The impedance bandwidths (|S11| <; -10 dB) of 7.3% and 12.7% are achieved at cen...
Dual-loop slot antenna with simple feed A dual-loop slot antenna consisting of two identical loops fed by a triplate line is proposed. It is experimentally demonstrated that the antenna radiates ... K Hirose,H Nakano - 《Electronics Letters》...
A novel dual-broadband circularly polarized folded slot antenna with single-feed is presented. The proposed antenna consists of two folded annular slots. By adjusting the asymmetric widths of the two slots, circularly polarized radiation can be achieved in two different bands. By optimizing the ...
