Abstract

The wireless sensor network system requires two antennas that have an output 90 phase difference as a comparison and use a very expensive material for high frequency. 5.5 GHz microstrip antenna frequency equipped with two output 90 degree phase difference in one antenna has been proposed. This is a new technique in telecommunication systems to produce directional antenna use more precise and efficient phase comparators by using cheap and easy to find material at 5.5 GHz frequency. This system package consists of a circular patch, a reflector, a double transmission line with a via hole that has the same frequency in one antenna and quadrature 90 degree hybrid coupler integrated each other. This antenna produces a phase angle difference 87.752 degrees (5 degrees of standard tolerance) and gains 5.82 dBi at 5.5GHz frequency. Overall size of the proposed antenna design is 90 mm times 35 mm with Phenolic White Paper - FR4 with a dielectric constant is 4.4.
