Novel Design of Microstrip Patch Antenna based on Two-Shape Structure
Recently, most of researches concentrate on design broadband and high gain microstrip antenna with a low profile to fulfill modern communication system requirements. This paper presents a novel design of microstrip patch antenna. The design is based on the number two (Two-Shape) shape using the Computer Simulation Technology (CST) microwave studio. The novel design is operated at the X-band frequency, and it provides a very wide bandwidth which is around 25 % at the center frequency 10.25 GHz. The antenna realized gain fluctuates between 5.3-7.7 dBi over the entire X-band frequency. The antenna provides a Fan- beam radiation patterns with very low side lobe levels, which are below -10 dB in both of the E- and H-planes. Due to the simplicity and compatibility, it is believed the antenna could be of interest to the radar applications.
