چکیده
This paper proposed a microstrip antenna array with DGS (Defective Ground Structure). The structure in this work is 2*1 microstrip patch array antenna using substrate with h= 0.762 mm and εr = 3.2. Two triangular-shaped patches are located on opposite side of PCB and spaced 14mm apart by a small ground portion. The proposed DGS of I-shape is placed in the ground plane. It does provide a method to improve antenna performance. In this way, return loss i.e., S11≤ 34.829dB at resonant frequency 9.60GHz is obtained. The proposed antenna is suitable for X-band applications such as satellite communications, medical applications, radar applications and other wireless applications. The analysis has been done by using IE3D software based on MOM (Method of Moments). Keywords— DGS, Microstrip Antenna, Array Antenna, Return Loss, Gain, Directivity, Antenna Efficiency, Radiation Efficiency.
