摘要：
This paper presents a compact dual-polarized dual-band stacked patch antenna suitable for WLAN. The dual polarization characteristic is achieved by using a cross-slot coupling feed. The designed antenna can operate in the high frequency band (5 GHz) by using a circular patch. Under the combined action of the circular patch, a narrow annular parasitic patch and a special barrel-shaped metal platform with the slotted sidewall, a good impedance matching in the lowfrequency band (2.45 GHz) is obtained. The metal platform not only serves as a reflector of the antenna, but also plays a key part in obtaining good impedance matching of the antenna at low frequency. The measured results demonstrate that the operating frequency of the antenna is 2.25-2.8 GHz (VSWR < 2.0) at low frequency band and 5.02-6.0 GHz (VSWR < 2.0) at high frequency band. Moreover, a stable radiation pattern is obtained.
