Abstract

Two types of MIMO antenna arrays are proposed, towards millimeter wave technology. The antenna resonances are at 77 GHz. This paper mainly discusses the decoupling of antenna in MIMO system. The first array antenna is microstrip feed patch MIMO antenna which unit is an elliptical patch. A decoupling branch is added in the middle to improve the isolation to less than −15 dB. The second MIMO array antenna is with a resonance frequency at 77 GHz which meets the Chebyshev distribution. We use series resonance feed, and 1 × 16 line array is used as the MIMO antenna unit. We increase the line array space to achieve an isolation of less than −20 dB in the antenna frequency band.
