Square Patch Micro-strip Antenna Using Dual Feed

The communication devices utilized the portion of the electromagnetic spectrum. The electromagnetic spectrum outside the visible region has been employed for communication by the use of radio wave. A two port Square Microstrip Patch Antenna is investigated in this paper. The antenna was designed for operating in S band (2 – 4 GHz) frequency range with a circular polarization. Microstrip patch antenna used to send onboard parameters of article to the ground while under operating conditions. The aim of the paper is to design and fabricate an probe-fed Square Microstrip Patch Antenna and study the effect of antenna dimensions length, and substrate parameters relative Dielectric constant, substrate thickness on the radiation parameters of bandwidth.
