提出了一种在方位平面内具有良好全向辐射性能的平面偶极子阵列天线。该平面偶极阵列天线包括两个1 /spl ×/ 2偶极阵列，该两个1 /spl ×/ 2偶极阵列背对背布置并由窄矩形接地平面隔开，并且该平面偶极阵列天线通过在电介质基板的两侧上印刷而容易地构造。在2.4 GHz频段（2400-2484 MHz）的无线局域网操作所提出的天线的原型进行了构建和研究。在方位角平面上获得了增益变化小于2dBi的良好全向辐射，并且在2.4GHz频带上测量的工作频率的最大天线增益约为5.0- 6.1dBi。研究了地平面宽度和阵列间距对天线性能的影响。
A planar dipole array antenna having good omnidirectional radiation in the azimuthal plane is presented. The planar dipole array antenna comprises two 1 /spl times/ 2 dipole arrays arranged back to back and separated by a narrow rectangular ground plane, and is easily constructed by printing on both sides of a dielectric substrate. Prototypes of the proposed antenna for WLAN operation in the 2.4 GHz band (2400-2484 MHz) were constructed and studied. Good omnidirectional radiation with gain variations less than 2 dBi in the azimuthal plane has been obtained, and the measured maximum antenna gain for operating frequencies across the 2.4 GHz band is about 5.0-6.1 dBi. Effects of the ground-plane width and the array spacing on the performance of the proposed antenna are also studied.
