In satellite communication, there are several types of micro-strip antennas, the most common of which is ?Micro-strip patch antenna?. Micro-strip patch antenna with slots placed parallel on the rectangular patch has developed and presented in this paper. Slots on the proposed patch can be used to increase the bandwidth of antenna. A constant radiation pattern with improved bandwidth, for an operating frequency of 4.5GHz can be easily achieved. Configuration of an antenna is easy to design. Different parameters like return loss which is -31.2492 at 4.7399GHz,gain along ?, ? directions, radiation pattern in 2D & 3D where the 2-D gain is 8.0082 dB, E (9.3322e+002 ),H (1.3894e+000) field distributions and current distributions (2.2219e+000) are simulated using HFSS 13.0. This type of proposed patch can be used for various applications in S,C ? bands.
