摘要：

In this paper, a novel structure of two interlaced antenna arrays for MIMO applications is presented. It consists of two 2 x 1 triangular patch array antennas, which have all elements separated by a short distance among them (0.22 lambda(0)), where mutual coupling can be very poor (S-21 = -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 1.56 lambda(0) x 0.3 lambda(0) and has a gain of 9.11 dBi. Its diversity parameters describe it as a useful radiator for MIMO communications systems.
