A quad-polarization and frequency reconfigurable square Frequency diversity characteristic is achieved using a PIN diode in the U-slot and the polarization diversities among linear polarization (LP), right-hand circular polarization (RHCP), and left-hand circular polarization (LHCP) are obtained by switching three PIN diodes placed on the slot and truncating corners of square patch. IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, … IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 54, NO. 2, FEBRUARY 2006 439 Pattern and Frequency Reconfigurable Annular Slot Antenna Using PIN Diodes Symeon Nikolaou, Ramanan Bairavasubramanian, Student Member, IEEE, Cesar Lugo, Jr., Student Member, IEEE, Pin diode in reconfigurable antennas - edaboard.com Aug 17, 2018 · Hello I am working on reconfigurable antennas.I have simulated one design with switching element as pin diode. It is easy to switch the pin diode during designing of antenna. How can we switch the pin diode after fabrication of antenna???Do we need any extra supply for that. If we add some supply to change biasing of pin diode,it will lead to a concept of multiple feeds to antenna. An Electrically Small CPW Fed Frequency Reconfigurable …
so that there is no coupling between these two polarizations. The switching speed of the PIN diodes is slower than the MEMS-based switches. Nanbo Jin designed the patch antenna [2] with switchable slot (PASS).This concept is implemented to design a novel reconfigurable antenna with both frequency and polarization diversities.
