Abstract
A multi-functional stacked microstrip patch antenna is introduced. The antenna operates at an upper frequency with a broadside pattern, 9 dBi right-hand circularly polarized gain, and 16% impedance and axial ratio bandwidth. At a lower frequency, the antenna operates as a planar inverted-F antenna with the main beam directed close to the horizon. Switching between the two regimes of operation is achieved using PIN diodes.
