摘  要：該文設(shè)計一款雙頻段MIMO印刷偶極子天線系統(tǒng)，由2個天線單元組成，每個輻射單元由2個不同尺寸的微帶開口環(huán)組成。通過在地板上開方形柵格，減少了2個天線單元之間的耦合，提高天線端口間的隔離度，在2個工作頻段內(nèi)隔離度均高于25 dB。

Abstract： A dual-band MIMO printed dipole antenna system is designed in this paper， which is composed of two antenna elements， each of which is composed of two microstrip open rings of different sizes. By opening a square grid on the floor， the coupling between the two antenna elements is reduced， and the isolation between the antenna ports is improved， which is higher than 25 dB in the two working frequency bands.

Keywords： multi-input multi-output （MIMO） antenna; isolation; dual-band; structural design; radiation direction
