A Novel Hybrid Reconfigurable Antenna for Portable Wireless Terminal Applications
In this paper, a dielectric embedded antenna with hybrid reconfigurable characteristics is proposed for portable wireless terminal applications, which is used as frequency or radiation reconfigurable antenna. The proposed hybrid reconfigurable antenna consists of a driven element, two parasitic elements and eight switches. By controlling the ON/OFF states of these switches set on the driven element, the proposed antenna can operate at two different frequencies, namely, 0.85 GHz and 1.9 GHz. The radiation reconfigurable characteristic is achieved by switching six switches installed on the parasitic elements. The proposed antenna has three modes of the radiation patterns at each frequency, has the potential to reduce noisy interference, and hence can improve the performance of the wireless systems. The simulation results demonstrated that the proposed antenna with flexible frequency and radiation pattern reconfigurable function is small in size and is promising for portable wireless devices.
