Abstract :
A dual-band base-station antenna with high gain is proposed in this letter. The antenna consists of a pair of planar patches and vertical shorted patches. Each of the two planar patches is composed of three U-shaped slots that differ in size. The bigger U-shaped slots that are connected to vertical patches operate at high frequency (3.5 GHz), and the smaller ones work at low frequency (2.4 GHz), which can be applied to wireless local area network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) operations. This antenna also exhibits high gains of near 8.0 and 11.0 dBi at the low and high working frequencies, respectively. Good cross-polarization performance is also verified by measured results. It is also demonstrated that the two working bands can be flexibly controlled by suitable changes of corresponding parameters of U-shaped arms.
