Abstract
In this letter, a miniaturized six port Multiple-Input Multiple-Output (MIMO) antenna is presented and evaluated based on simulation. The proposed antenna consists of three planar inverted-F antennas (PIFA) and three notch antennas. The combination of these elements yields low mutual couplings among them since electric field directions of them are orthogonal to each other. Furthermore, PIFA and notch antenna are miniaturized by using T-shaped conductor and loading reactance, respectively. From the antenna characteristics results, it is found that all mutual couplings were suppressed less than −10 dB. From the channel capacity characteristics results, the channel capacity was improved by 10.62 Bits/s/Hz compared with six dipole antennas with same aperture width of the proposed antenna.
