Abstract
This paper focuses on the design of a thinned array antenna using microstrip patch, which is a novel task in recent years. The aim of thinned array antenna synthesis is to obtain a desired radiation pattern with a minimum number of antenna elements. For uniform spacing array antenna, a certain number of elements can be removed, while maintaining a desired radiation pattern using genetic algorithm optimization. Parameters such as beamwidth and side lobe level are evaluated for proposed thinned array antenna by comparison with those obtained for different types of uniform array antennas. Numerical examples are presented to show the high energy efficiency of the proposed thinned array antenna.

Technology and science have made major changes to the way we live, with the development of high-tech, scientific challenges and changes come along with it
Antenna plays an important role in such communication system, and its radiation characteristic affects the overall system. e microstrip patch antenna is widely used in varies communication systems; it is attractive due to its thinned profile and light weight, being simple to manufacture, being integrated with circuit, its low cost, etc
To reduce the manufactured cost of PCB, the thinned array antenna is designed on the low-cost Fr-4 substrate in International Journal of Antennas and Propagation which the thickness is 0.2 mm, dielectric constant is 4.2, and the loss tangent is 0.02; the proposed thinned array antenna is fabricated and measured to verify the theoretical expectation
Summary
Technology and science have made major changes to the way we live, with the development of high-tech, scientific challenges and changes come along with it. E research on thinned array received extensive concern in communication engineering in recent years; relative papers provide useful results [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]. Most of these researches study thinned array antenna based on the assumption of no coupling effect which occurs between antenna elements and using infinitesimal point to represent antenna radiator. To reduce the manufactured cost of PCB, the thinned array antenna is designed on the low-cost Fr-4 substrate in International Journal of Antennas and Propagation which the thickness is 0.2 mm, dielectric constant is 4.2, and the loss tangent is 0.02; the proposed thinned array antenna is fabricated and measured to verify the theoretical expectation
