Abstract :
A novel design of a circular patch antenna with a square shaped defect in the ground is presented in this communication. The antenna operates in L-band and is applicable for wireless communications. Square shaped defect is introduced diagonally in the ground plane. A comparison is also presented for the antenna structures without defect and with defect. Parameters like impedance bandwidth and antenna gain are calculated and discussed. Impedance bandwidth of about 15 % is obtained for the defected ground structure (DGS).
