| Popis: | In this paper, we present two integrated rectifier-antennas (rectennas) which maximize received DC power for 1µW/cm2 incident power density at 2.45 GHz. One of the rectennas is an air-substrate patch, 58 × 10mm2 in area, with a ground plane that is only slightly larger than the patch and a 3-mm thick air spacer, resulting in a gain of 7.2 dBi. A single diode rectifier is directly matched to the complex antenna impedance in both cases. The second rectenna is a printed version of a coaxial collinear array, 261mm × 5mm in area and a 3-mm air substrate. The two rectennas have comparable antenna gain of 7 dBi, rectified power of 15 to 25µW and efficiency of 30%. |
