摘要：

This paper deals with the implementation of Dolph-Chebyshev window on a proximity-fed circularly polarized array slotted square patch antenna to attain side lobe level (SLL) suppression. The need of array antenna with suppressed SLL is sometimes required for enhancing the reliability of communication. The proposed array antenna is intended for 5GHz band wireless communication and consists of 5 square patches deployed on 2 layers of 0.8mm thick FR4 epoxy dielectric substrate. The array antenna is expected to produce circularly polarized wave by applying diagonal slots upon each square patch. While the proximity couple feed is used to enhance radiation properties of the array antennas. The characterization results could achieve the SLL of 12.39dB, the gain around the frequency of 5.3GHz of more than 6dBi, and the 3dB axial ratio bandwidth of 200MHz.
