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.When a PIN diode is forward biased it behaves, in AC, like a variable resistor. The value of its resistance depends from the DC current flowing into the...
