Simulation, measurement with hard-wired short, ... direction using two PIN diodes placed at. 225 o and 315o.The 90 o 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.
