As a proof of concept, two pin diodes are placed 45 on both sides of the feeding line along the ASA and the direction of the null is shown to align with the direction defined by the circular slot center and the diode. Consequently, a design that is reconfigurable in both frequency and radiation pattern is accomplished.

Hi normally we use PIN diodes for pattern reconfigurable antenna. My question is that as the current in antenna is ac how does the PIN diode works. Because diodes only let current flow only in one direction? When a pin diode is forward biased does it allow the ac current to flow in both direction?

Pin diode in reconfigurable antennas - edaboard.com 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.
