A Reconfigurable Polarized Antenna Using Switchable Slotted.

. Slot antennas are very popular microwave antennas, and slotted waveguides are used for high frequency radar systems. A thin slot in an infinite ground plane is the complement to a dipole in free space. This was described by H.G. Booker, who extended Babinet#x27;s principle from optics to show that the slot will have the same radiation pattern as a dipole such that the E and H fields are..
