摘　　要：提出了一种小型化的用于WLAN/WiMax通信系统的多频带印刷单极子天线。通过改进双"G"形的振子结构,使天线能在2.4 GHz,3.5 GHz和5.5 GHz谐振,实现2.4/5.2/5.8 GHz WLAN和3.5/5.5 GHz WiMax频带的覆盖。对加工后的天线模型测试表明,天线在工作频带内具有较宽的阻抗带宽和较好的辐射特性。因此,该天线可以应用在多频带无线通信系统中。A compact printed monopole antenna is proposed for WLAN and WiMax applications. Impedance bandwidths covering 2.4/5.2/5.8 GHz WLAN and 3.5/5.5 GHz WiMax bands are obtained by using a modified du- al G-shaped strip. Omnidirectional radiation patterns over the operating bands of a fabricated antenna are obtained, which shows that the antena has great impedance bandwith and good radiation characteristics, and is suitable for multi-band wireless communication applications.
