摘要

In this article, a three-port nonplanar multiple-input-multiple-output/diversityantenna with very high isolation between the radiating elements is presented. Torealize diversity from the proposed three-dimensional (3-D) antenna configuration,three monopole radiating elements are arranged at an angle of 120. The isolationbetween the radiators is enhanced by using a multilayered cylindrical decouplingstructure and defected ground structure (DGS). The DGS reduces the coupling dueto surface waves while the cylindrical decoupling structure reduces the couplingdue to space waves. The proposed antenna offers consistent pervasive connectivityin the wireless communication environment due to its 3-D geometry with multipleradiating elements and good diversity performance. The prototype is fabricated andmeasured result shows that more than 42 dB isolation is obtained at the center frequency1.45 GHz. An increment of 1.2 dBi in the antenna gain is also achieved byusing DGS and decoupling structure arrangement. The proposed antenna can beeasily placed inside the cylindrical housing or it can be integrated with the existingelectronics chip, thus nullifying the requirement for dedicated location in thesystem.
