摘要 由于微带天线的频带较窄,故在很大的程度上限制了微带天线的广泛应用。文中给出了一种由三层多贴片组成的宽频带微带天线,它利用微带线进行馈电,放4个圆形贴片在中间层作为补偿电容。由贴片之间的谐振耦合使该天线的频带展宽25.79%(VSWR≤2),可在从14.15G到18.34G的Ku波段内工作。 Due to the bandwidth of a micro-strip antenna being narrow, its usage is limited to a great extent. This paper presents a kind of sample and practical micro-strip antenna composed of three layers and two square patches. It is fed with micro-strip lines and has four circular patches used as the compensatory capacitances in the middle layer. Since there exist resonance with a coupling between the patches, the bandwidth of the micro-strip antenna is extended to 25.79% under the condition of VSWR≤2, the simulation results show that it can work very well within Ku band from 14.15GHz to 18.34GHz.
