Polarization Switchable Microstrip Antenna Using PIN Diodes(Antenna and Propagation) JUNG Dongkeun FUKUSAKO Takeshi KITAMURA Naoki MITA Nagahisa HA Cheunsoo 社団法人電子情報通信学会 IEICE transactions on communications 09168516 87 1 152 157 2004-01-01 A polarization switchable slot-coupled microstrip antenna using PIN diodes is proposed and studied. The microstrip feed line installed behind the ground plane is divided into two branches and each tip of the branches is connected to the ground plane through a PIN diode. One of the diodes is oriented from the tip to the ground plane and the other is oriented from the ground to the tip so that a slot in the ground can be selected to feed the patch by switching the dc bias between positive and negative. This selection contributes to switch the polarization between horizontal and vertical. In this paper, the authors investigate the polarization switching antenna theoretically and experimentally and confirmed sufficient difference of antenna gain between horizontal and vertical polarization. 2004-01-01 110003222064 AA10826261 ENG CJP CJPref NII-ELS 1 5 3 Polarization Switchable Microstrip Antenna Using PIN Diodes(Antenna and Propagation) JUNG Dongkeun FUKUSAKO Takeshi KITAMURA Naoki MITA Nagahisa HA Cheunsoo The Institute of Electronics, Information and Communication Engineers IEICE transactions on communications A polarization switchable slot-coupled microstrip antenna using PIN diodes is proposed and studied.
