A wideband circularly polarized microstrip patch (CP MPA) antenna directly coupled with single feed structure is proposed for wide axial ratio bandwidth (AR BW). The antenna is basically designed for circular polarization and is composed of suspended near square patch with diagonal single feed. The near square patch is directly coupled with two neighbour parasitic patches. By loading a shorting pin in the diagonal of the parasitic patch, wide AR BW and high gain is obtained. The design is carried out at the 3 Ghz as centre frequency. The proposed antenna is fabricated and measured for radiation patterns. The square patch with two nearly square parasitic patches has been directly coupled. This configuration has a simulated and measured, 10dB return-loss bandwidth (RL BW) of 13.3% and 16.06% respectively. This configuration yields simulated 3 dB AR BW of 6.79%, with an average gain of 8.5dBi across the AR frequency range with the above defined centre frequency.
