Abstract :
Several electrically small, metamaterial-inspired near field resonant parasitic (NFRP) antennas are designed for operation at the GPS L1 frequency (1.5754 GHz). Their intended use is in a rectenna system. All these antennas are based on the electric coupling between the NFRP element and the driven monopole element. They are designed to be matched to a 50Ω source. The simulated results of the magnitude of S11, radiation efficiency, radiation patterns, and Q ratio are provided. Comparisons between the performances of these antennas are given; experimental confirmation of these simulation results will be provided in our presentation.
