A reconfigurable patch antenna with symmetrical structure for polarization diversity is proposed in this article. The proposed antenna mainly consists of a rhombus-shaped patch with single feed, two conductive pads with via hole and two PIN diodes. The antenna can produce right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) by adjusting bias state of two PIN diodes. The...
In this paper, a reconfigurable antenna for WWAN (Wireless Wide Area Network) mobile handset application is proposed. The proposed antenna consists of a conventional PIFA, a parasitic line, a PIN diode, and a bias line. When PIN diode is the on-state, the measured results show that the −6 dB reflection coefficient bandwidths are 8.15% (824–894 MHz) at low band and 34.12% (1580–2230 MHz) at high band...
