In this letter, a design method of a simple decoupling network (DN), which decouples adjacent antenna ports for n-element linear array antenna, is presented and evaluated based on simulation and measurements. In our technique, microstrip line (MSL) is used to configure DN. MSLs work as bridge susceptances and are connected between two adjacent antenna ports, and they decouple the antenna ports by means of cancelling the mutual admittance. From the experimental results, it is found that the mutual coupling less than -30dB between adjacent antenna elements is achieved by using proposed design method.
