The present day Systems are operating in two or more frequency bands, requiring Dual or even triple band operation with narrowband antennas. This requirement is demanding a lot more of research in the field of antenna design. These include GPS, Satellite navigation system, wireless cellular system and LANs. Recent advances in the software defined a...

... When designing the antennas, as a rule, is ignore the estimated location and the influence of surrounding structural elements on their radiation characteristics [1][2][3]. In the result of the characteristics of antennas installed on a particular object, can be very different from those which were obtained at the stage of development and production design. ...
—A small ring antenna working at 2.45 GHz was designed in this paper, a small disk-coupled structure was applied to feed an inner-hole-biased ring patch, contributing to not only improving the impedance characteristics of the antenna but also reducing the size. The simulation results show that the designed patch area is only 70.7% of that of the traditional circular microstrip antenna on the premise of ensuring good bandwidth and gain performance; the −10 dB bandwidth of S11 parameter is 62 MHz; the gain of the maximum direction is 7.11 dB; and the circular polarization of the antenna is also realized. This design has also been compared with several conventional designs. It is proved that the antenna has good comprehensive performance, and the antenna feed structure is simple, easy to process, very conducive to engineering applications. Finally, the feasibility of this technology was verified by contrasting the measured data with the simulation data.
As the technology in wireless communication field is advancing rapidly the need of an antenna with high accuracy is required. This research paper represents Microstrip patch antenna working on L band for satellite communication which resonates at 2.4GHz frequency. For this antenna coaxial feeding method is used. Parameters like Bandwidth, Gain and Return loss are analysed for this antenna. The HFSS 13.0 software is used for design and simulation.
