In this paper, a novel design of a corrugated microstrip antenna with wideband characteristics is proposed. The suggested antenna consists of an arc-shaped edge and a ground plane which has been modified. The difference from the other traditional antennas is in the modification of the ground plane. The corrugated ground plane is present below the feed line and partially present just below the radiating element. By cutting square shaped slots on the arc side at regular intervals improves the frequency bandwidth. With this design the return loss curve was found to be below -10dB with frequency range of 2.6-17.7GHz and a radiation pattern just like a horizontal dipole antenna.
