A Simple T-shaped Wide-band Slot Antenna for Rectenna System

This paper proposes a simple T-shaped wideband slot harmonic suppression antenna at 2.45 GHz. Harmonic suppression is achieved by using a narrow T-shaped conductor line. This antenna is simple and easy to design. Considering the wideband with harmonic rejection and relative high gain, it's a good candidate for rectenna system. The return losses of the antenna at the fundamental and harmonic frequencies are simulated and studied by CST.
