Abstract :
A frequency reconfigurable hexagonal patch antenna with switchable slot is proposed in this paper. By changing the slot status, two resonant frequency bands at 2.29GHz and 2.46GHz respectively can be obtained without special matching network, and the radiation patterns at the two frequency bands are very similar to each other. The simulated and measured results are presented to validate this concept, which could be used for bandwidth enhancement. This proposed antenna is interesting for wideband wireless applications because of its low profile, light weight and easy fabrication.
