Radiation Characteristics and Mutual Coupling of a Dual: Band Antenna Array Structure

In this paper, an antenna array structure consisting of a reflector plate and a number of printed dipole radiation elements is investigated. This antenna array implementation is suitable for the globally available 2.4GHz and 5GHz ISM frequency band facilitating a variety of wireless applications. S-parameters and radiation characteristics are simulated and measured in details. The impact of the plane reflector on radiation patterns and the reflection coefficient are also investigated. Furthermore, mutual coupling effects between adjacent elements and the corresponding radiation patterns are studied for different antenna array configurations. Both simulated and measurement results are useful in antenna array design and antenna applications in wireless communications.
