Novel microstrip antenna element and 2-by-2 array for satellite TV receivers

A new microstrip antenna element is presented in this article. The proposed antenna is suitable for integration into an array for satellite TV receivers. It has two metal layers only, which reduces its fabrication cost significantly in comparison with other antennas with more layers. The presented results show that the proposed antenna offers wide impedance bandwidth, high isolation between feeding ports, dual‐polarization radiation, low cross‐polarization level, and high radiation efficiency. A 2‐by‐2 array based on the proposed element is also presented in this article. Planar corporate feeding networks with new routing approach are used. The presented results of the new array show that it is suitable for use as a building block for a larger array which can repalce the parabolic dish reflector in satellite TV receivers. © 2008 Wiley Periodicals, Inc.
