Designing of S Shaped Microstrip Patch Antenna for Broadband Application Using Slotting Technique

Microstrip patch antennas get more and more important in these days. This is mostly due to their versatility in terms of possible geometries that makes them applicable for many different situations. The light weight construction and the suitability for integration with microwave integrated circuits are two more of their numerous advantages. Additionally the simplicity of the structures makes this type of antennas suitable for low cost manufacturing. And this is also one key feature of microstrip patch antennas are used in mobile communications applications. Thus the size reduction and bandwidth enhancement are becoming major design considerations for practical application of microstrip antennas. The purpose of this paper is to design a dielectric substrate, fr4 substrate for high bandwidth microstrip patch antenna and to compare with the former patch antennas and then proposed the better one. In this research work, we have designed the S-shaped slotted patch antenna. Here bandwidth is obtained 38 % of the center frequency which is the extremely large than the parasitic patch antenna. Microstrip Patch Antennas (MPA) are extremely attractive candidates for use in many applications due to their interesting features such as low cost, light weight, thin profile and conformability. A 3D field solver is used to simulate the performance of the proposed antenna by inputting the sizes of the physical structure. Coaxial probe feeding technique is used to feed the antenna. ADS (advanced desidn system) software simulator software are used to design and simulate the proposed patch antenna.
