Abstract As the Modern communication system is upgrading day-to-day, present most of the communication is based on satellite communication and other wireless communication systems. Satellite communication offers high data rates for faster communication and mostly it provides a secure way of communication but these Satellite communication mainly operated at higher band of frequencies like Ku, K & Ka bands. To operate at such higher frequency bands we need a Micro-Strip patch antenna due to its light weight and simple in construction structure. Considering the design of patch shape, different patch shapes are available in Micro-strip antennas like Rectangular Micro-strip patch antenna, E-shape Micro-Strip patch Antenna and Elliptical shaped Micro-Strip Patch Antenna. The above mentioned patch shapes in micro-strip antennas are mainly affecting 3 parameters, they are Return loss, VSWR and Gain. These patch shapes in micro-strip Antenna offers high value of Return loss which in turn increases VSWR value and lowers the Gain of the antenna while operating at Ka band frequencies. This paper presents the design of S-shaped Micro-Strip patch antenna; here the shape of the patch looks like S alphabet. This S-shaped Micro-strip patch antenna is used to overcome the defects present in the Rectangular Micro-strip Patch Antenna, E-shaped micro-strip patch antenna and Elliptical shaped Micro-Strip Patch Antenna at Ka band of frequencies. In this work, we propose the S-shaped Micro-strip patch antenna made up with substrate material Bakelite, which provides better gain, less return loss and low VSWR value for high frequency band like Ka band when compared with other conventional patch shapes mentioned above. The design and analysis of the S-shaped Micro-strip patch antenna is carried out by using CST software tool.
