In this article, HIS-like resonators are proposed for mutual coupling reduction between the elements of a small array. First, a methodology is proposed for the design of HIS-like resonators. Then, a reference array made of two cavity backed patches working in L-band is designed. HIS-like resonators are then introduced in the array in order to reduce couplings between the patches in E-plane configuration. These two arrays are then manufactured with modular parts, providing the possibility to replace the patches and tune the HIS-like resonators resonant frequency. Simulated and measured S-parameters are illustrated, showing the capability of these structures to reduce significantly mutual couplings.
