A study of printed monopole antenna for ultra wideband systems
نویسندگان
چکیده
A printed monopole antenna with CPW-fed is proposed. The proposed antenna includes a rectangle shape radiator, two ground planes with symmetrical notch and feed excitation. It covers the all ultra wideband (UWB 3.1GHz ~ 10.6GHz) and has 7.8GHz (2.8GHz ~ 10.6GHz) measured return loss bandwidth. In modifiable design, we choose to design the notches on the ground plane, the high of the proposed antenna and the width of the radiator, and have to obtain broad impedance bandwidth and accessible measurement parameters. The experiment results have shown omnidirectional radiation pattern and fine gain over UWB operation in this paper.
