Abstract
In this paper, a novel structure of two interlaced antenna arrays for MIMO applications is presented. It consists of two 2x1 triangular patch array antennas, which have all elements separated by a short distance among them (0.22λ0), where mutual coupling can be very poor (S21 = –7.81 dB). To overcome such weakness, a simple and efficient method is used: one neutralization line (NL) is introduced to increase the decoupling between both ports, reaching up to –29 dB at the central frequency, and below –20 dB over a large bandwidth. The whole MIMO antenna array has dimensions of 1.56λ0 × 0.3λ0 and has a gain of 9.11 dBi. Its diversity parameters describe it as a useful radiator for MIMO communications systems.
