A novel planar antenna integrated Bluetooth and multi-band ultra-wideband antenna is presented. This antenna is electromagnetically coupled to the feed microstrip-line on one side of the dielectric substrate, and through a via-hole, to a radiating element in the ground plane. By inserting a triangular slot inserted in the ground plane, a much wider impedance bandwidth from 2.7-15-GHz is realised....
A compact printed monopole antenna using two U-type slot working at Bluetooth/WiMAX/WLAN service is present. The antenna can be implemented with a small dimension similarly to the conventional strip-type slot. Based on the simulation and measurement results, triple-band antenna using two U-type slots are very effective in rejecting unwanted frequency in terms of its selectivity and small real estate...
