摘　　要：针对2.4/6 GHz双频WLAN应用,提出了一种具有全向辐射模式和定向性的机械模式可重构双频天线。通过手动旋转顶部基板,天线可以分别在贴片状态或单极状态下工作。介绍了一种由外贴片、内贴片和U型间隙组成的新型U型间隙结构,实现了两种工作状态下的双频特性。这两个状态的测量重叠带分别为2.4~2.56 GHz和5.66~6.36 GHz,以及2.32~2.45 GHz和大部分5.71~6.33 GHz WLAN频段。测量的峰值增益在2.5 GHz时为7.0 dBi,在6 GHz时为8.09 dBi,在2.5 GHz时为2 dBi,在6 GHz时为6.74 dBi。For 2.4/6 GHz dual-band WLAN applications,a reconfigurable dual-band antenna with omnidirectional radiation mode and directional mechanical mode is proposed.By manually rotating the top substrate,the antenna can work in patch state or monopole state respectively.A new U-type gap structure consisting of outer patch,inner patch and U-type gap is introduced.The dual-frequency characteristics under two working conditions are realized.The measurement overlap bands of these two states are 2.4~2.56 GHz and 5.66~6.36 GHz,respectively,and 2.32~2.45 GHz and most of the 5.71~6.33 GHz WLAN bands.The measured peak gain is 7.0 dBi at 2.5 GHz,8.09 dBi at 6 GHz,2 dBi at 2.5 GHz and 6.74 dBi at 6 GHz.
