Abstract :
The correspondence presents a chip antenna for ultrawide- band (UWB) radios. The chip antenna is realized with a simple radiating element and small ground plane in low temperature cofired ceramic (LTCC) technology. The chip antenna has size 17 X 8 X 0.8 mm3 and achieves impedance bandwidth from 3.75 to 10.45 GHz and gain from - 2 to 2.3 dBi over this frequency band. The measured radiation patterns are presented and small group-delay variations are found at the UWB frequencies from 3.1 to 10.6 GHz.
