This research work presents a planar compact electromagnetic bandgap (EBG) structure with the potential to reduce the mutual coupling between the elements of a microstrip antenna array The proposed structure is investigated at 559 GHz, which is the centre frequency of the wireless local area network band To achieve the highest radiation performance for microstrip antenna arrays, with minimal inter-element spacing and mutual coupling, different unit cell arrangements were considered along with two adjacent patch elements The simulations and measurement results for the proposed arrangements indicate that the mutual coupling tends to diminish significantly For instance, when adjacent patches are spaced by 04
λ
, the mutual coupling improves by ~25 dB For the particular spacing of 04
λ
, it is favourably observed that the proposed EBG cells can also improve the antenna gain by ~25 dB Such improvements can be attributed to the compactness of the cells (~
λ

TL;DR: It is shown that the mutual-coupling reduction methods inspired by MTM and MTS concepts can provide a higher level of isolation between neighbouring radiating elements using easily realizable and cost-effective decoupling configurations that have negligible consequence on the array’s characteristics such as bandwidth, gain and radiation efficiency, and physical footprint.
