Abstract
A modified U-slot patch antenna that is capable of switching among linear, right-handed circular, and left-handed circular polarization is proposed. The main contribution of this work is the proposal of a simple integrated dc bias circuit for U-slot patch to enable independent control of the two pin diodes. Meanwhile, the resonant current distributions with and without the bias circuit remain nearly the same for all polarization states. To verify the feasibility of our proposed design, a 2.4-GHz prototype antenna is designed, fabricated, and tested. The measured results agree excellently with those simulated.
