A monopole antenna with a magneto-dielectric material and its MIMO application for 700 MHz-LTE-band

This article presents an antenna with a magneto‐dielectric material and its MIMO application for LTE‐band.The proposed antenna is a folded monopole type and occupies a compact volume of 7.5 × 18.5 × 3.4 mm3. For reducing the size, obtaining the broad bandwidth, and enhancing the isolation performance, the magneto‐dielectric material is applied as a supporter. The parameters of the magneto‐dielectric material are ε′ − jε″= 3.29−j0.09 and μ′ − jμ″ = 2.01−j0.38 at 780 MHz. For evaluations of the MIMO application, the antenna has been measured in reverberation chamber. The Microwave Studio (MWS) is employed for optimizing the design parameters, and the simulated results are well agreed with those of the measured one. © 2010 Wiley Periodicals, Inc.
