Abstract: In compact arrays, tight element spacing results in strong mutual coupling. This may cause severe system performance degradation. The effects of the coupling can be alleviated through the introduction of a decoupling network. An alternative solution comprises of a multi-port feed network which excites the antenna elements in accordance with the eigenvectors of the scattering parameter matrix of the array. This paper describes the design of a novel 4- element monopole array. The modal feed network of the array is implemented as a planar ring-type circuit in stripline with four coupled line sections. This implementation offers a significant reduction in size, resulting in a very compact adaptive array. © 2008 IEEE.
