Abstract :
The compactness of antenna arrays is highly restricted due to the mutual coupling effect between radiation elements, which degrades the arrays´ performances with respect to impedance matching, radiation efficiency, and antenna diversity. A two-port compact printed monopole antenna array with a novel and simple decoupling structure based on partially extended ground plane applicable for small terminals is presented. The distance between the printed monopole elements is less than 0.25λ. A broad matching and decoupling bandwidth up to 1.5 GHz (5.1-6.6 GHz) is achieved. The approach is proven by both simulations and measurements.
