The paper is presented analysis, design and manufacturing single optimize parameters of a new broadband elliptical patch antenna with microstrip center feed line and the array has been implemented to improve gain antenna. The antenna array dimension of mm 3 and fabricated on an FR-4 epoxy substrate having relative dielectric constant =4.3, loss tangent tan (δ) =0.002 and the feed line used has characteristic impedance of 50Ω and added the triangle notch structure .Thus notch can achieve maximal additional enhancement impedance bandwidth are (3.679- 6.578) GHz, (13.84-25.142) GHz, (29.807-37.618) GHz and the gain 8dBi. The antenna array performance was modified by inserting stubs transition in feeding Microstrip line to reducing mutual coupling achieve impedance bandwidth (when S 11 -10dB). The modified antenna was designed to be used for wireless communication application. The simulation results are obtained using CST software.
