Design and implementation of 2.6 GHz Phase shift using microstrip technology for mobile broadband application

This paper evolves transmission line phase shifting to optimize system cost. The design of a 1 x 2 microstrip (patch) array antenna which has an operating frequency of 2.6 GHz. Substrate FR4 dielectric with dielectric constant of 4.4 and thickness of 1.6 mm is utilized in array design. The study is performed in four steps: Firstly, through simulating radiation pattern on CST by altering two independent parameters; Spacing between patches and differential length of transmission line from source to each patch antenna. Secondly, a fabrication has been done on a sample deferential length to two ports that simulating two microstrip (patch) antennas array. Thirdly, testing of radiation fields has been performed to verify the correlation between actual records and the simulated designed antenna phase shifting. Fourth and finally, A comparison of results has been included between this paper results and previous works in sake of showing the introduced effort added value
