【 摘 要 】

References(11)Cited-By(3)A dual-feed circularly polarized antenna with built-in harmonic-rejection capabilities is presented for the first time. The square patch antenna has been designed at 5.8GHz and incorporates both circular polarization and harmonic-rejection in a single design, thus eliminating the need of a low-pass filter. A comparison among the proposed antenna, a simple square patch antenna, and a truncated square patch antenna is performed to evaluate the capabilities of the proposed design. The realized antenna exhibits a reflection coefficient of -1.92dB at the second harmonic frequency of 11.6GHz, and circular polarization for elevation angles in the range of -600 to 600, well suited for a rectenna in wireless power transfer applications.
