In this paper, high impedance periodic structure (HIPS) is applied to improve radiation pattern of the antenna element. The working mechanism of HIPS array is investigated. The structure could improve the surface-wave and the broad-beam radiation performance of the individual antenna element. It is benefit for the wide scan performance of the phased array. A microstrip antenna is fabricated and measured...
A synthesis method based on differential evolution algorithm is proposed for conformal antenna arrays in the presence of platform. With the desired phase weights determined by the scan angle and array geometry, the amplitude weights of elements are optimized by differential evolution algorithm to drive down the side-lobes. Both the effect of platform on radiation pattern of conformal array and the...
Phased array antennas have found an increased application in radar and, more recently, in satellite and cellular communications. The most recent application concerns smart antennas in cellular base stations. Despite increased popularity, the design and development of a planar phased array antenna remains a challenging task. In this paper, a high preference phased antenna array is designed. Compared...
