Design of CPW-fed asymmetric slot UWB antenna for wireless application | Journal of Electronics (China)
A compact Ultra-WideBand (UWB) slot antenna is presented in this paper. The slot is modified rectangular in shape and asymmetrically cut in the ground plane. A hexagonal patch with two stepped CoPlanar Waveguide (CPW) feed is used to excite the slot. Wider impedance bandwidth is achieved due to the extra inductive reactance created by the asymmetric slot which neutralizes the capacitive reactance of the hexagonal patch. The measured impedance bandwidth of the proposed antenna is 11.85 GHz (2.9–14.75 GHz). The radiation patterns of the proposed antenna are obtained and found to be omni-directional in H-plane and bi-directional in E-plane.
Lecture 5: Polarization and Related Antenna Parameters
The polarization of an antenna is defined as the polarization of the field transmitted by the antenna regardless whether it's in the transmitting or receiving mode.
