A Novel Compact Frequency and Polarization Reconfigurable Slot Antenna Using PIN Diodes for Cognitivngrossment. In this chapter, the proposed design has a straightforward and effortless construction. A simple rectangular microstrip patch cut by slot and the patch interconnect with four L-shaped strip lines. By enabling/disabling (ON/OFF) the (HPND4005) PIN diodes, the antenna operates at different
