Improvement in bandwidth using multidielectric patch antenna

The aim of the paper is to improve the bandwidth of the microstrip patch antenna. In this paper patch antenna using multidielectric layer is designed which improves the bandwidth. This antenna can be used for the X-band (10 GHz) applications. The improved bandwidth can overcome the inherent limitations of the microstrip patch antenna i.e. the low bandwidth. Design of the multilayer patch antenna with suitable permittivity and height of the substrate gives the desired result. Also, analysis and comparison of the design with and without dielectric layer is performed. Analysis based on the return loss, bandwidth and efficiency are also done. The simulations are performed on the ADS Tool.
