Abstract

A multi-functional stacked patch antenna is introduced for a possible wireless power beaming and data telemetry application. The proposed antenna operates at 5.8 GHz with 10 dBi gain, and 18% bandwidth. At a lower frequency, around 2.45 GHz, the antenna operates as a planar inverted-F antenna (PIFA) with 4 dBi gain and 3.2% bandwidth. Switching between the two regimes of operation can be achieved using PIN diodes. It is proposed that the antenna can be used for wireless power reception in sensors at 5.8 GHz and for data telemetry between sensors or between sensor and control station at 2.45 GHz.
