  Abstract

This study proposed a patch antenna with a MIMO structure which is applicable for wireless communication equipment by combining a single patch antenna with a multi port. The proposed MIMO patch antenna was designed through the TRF-45 substrate with a relative permittivity of 4.5, loss tangent equal to 0.0035 and dielectric high of 1.6 ㎜, and the center frequency of the antenna was 2.45 ㎓ in the ISM (Industrial Scientific and Medical) band. The proposed MIMO patch antenna had a 500 ㎒ bandwidth from 2.16 ∼ 2.66 ㎓ and 24.1% fractional bandwidth. The return loss and VSWR were -62.05 ㏈, 1.01 at the ISM bandwidth of 2.45 ㎓. The Wibro band of 2.3 ㎓ was -17.43 ㏈, 1.33, the WiFi band of 2.4 ㎓ was -31.89 ㏈, 1.05, and the WiMax band of 2.5 ㎓ was -36.47 ㏈, 1.03. The radiation patterns included in the bandwidth were directional, and the WiBro band of 2.3 ㎓had a gain of 4.22 ㏈i, the WiFi band of 2.4 ㎓ had a gain of 4.12 ㏈i, the ISM band of 2.45 ㎓ had a gain of 4.06㏈i, and the WiMax band of 2.5 ㎓ had a gain of 3.9 6㏈i.
