摘要

介绍了一种采用50 ω微带馈线，在电子薄介质衬底同侧印刷两个单极条的天线设计。该天线可提供450 MHz(约17.5%以2.575 GHz为中心)和1 GHz(约18.5%以5.4 GHz为中心)两个独立的阻抗带宽，回波损耗S11低于-10 dB。它很容易覆盖无线局域网(WLAN)所需的带宽。双频天线设计简单，天线的大条带和小条带的长度可以方便地分别控制较低和较高的谐振频率。通过改变辐射单元的宽度来获得更好的阻抗匹配。提出并讨论了天线设计的细节和结果。

A Novel Compact Dual-band Printed Monopole Antenna

The design of an antenna, consisting of two strip monopoles printed on the same side of an electronically thin dielectric substrate and using 50 Omega microstrip feed line, is presented. The proposed antenna can provide two separate impedance bandwidth of 450 MHz (about 17.5% centered at 2.575 GHz) and 1 GHz (about 18.5% centered at 5.4 GHz) with return loss S11 below -10 dB. It easily covers the required bandwidths for wireless local area network (WLAN). The dual-band antenna is simple in design, and the lengths of the antenna's larger and smaller strips can easily control the lower and higher resonant frequencies, respectively. The widths of the radiation elements are changed to get better impedance matching. Details of the proposed antenna design and results are presented and discussed.
