| Summary: | This paper proposes a receiving array antenna with a trapezoidal configuration that combines multiple rectifier circuits for wide-angle reception. The proposed receiving antenna system consists of three antenna elements operating at 5.8 GHz and the same number of rectifier circuits. To resolve the degradation in power transmission efficiency caused by misalignment, the receiving array antenna is designed in a trapezoidal configuration, and a quasi-air substrate is adopted for each antenna to achieve a high gain with the required beamwidth. All antenna elements in this system have measured reflection coefficients of less than −10 dB, and the overall beam coverage of the system is 205°. The power measurements of the receiving system are performed at 5° intervals within the beam coverage, and the results demonstrate that power is reliably received within the beam coverage through the proposed receiving antenna system. |
