A Wideband Planar Monopole Antenna Array with Circular Polarized and Band-Notched Characteristics

A wideband circular polarized Planar Monopole Antenna Array (PMAA) that employs dual band-notched characteristics is presented in this paper. The proposed antenna array is formed by four pinwheel-shaped folded Planar Monopole Antennas (PMAs) in order to improve the performance of circular polarization and high directivity. Also, it achieves low-profile, small-sized structure. The attractive characteristics of the proposed PMAA are a wide impedance bandwidth of 87.3% (1GHz to 2.55GHz), the 3dB Axial-Ratio (AR) bandwidth of 92.3% (1.05GHz to 2.85GHz) excluding dual notch bands, the total bandwidth of 35% (1.8GHz to 2.55GHz), and the maximum gain of 8.24dBic within the total bandwidth
