摘　　要：以WlFI和蓝牙技术为应用背景，设计了1种基于Alford环天线结构的水平极化全向天线，天线印刷在1块半径只有18mm的相对介电常数为2．65的圆形介质基板上，尺寸小重量轻。天线采用开槽形式并且增加寄生结构，使其在2．4GHz频率处具有良好的阻抗特性和全向特性，不圆度只有0．9dB。该天线可应用于室内及短距离范围内的终端通信。A horizontally polarized omnidirectional antenna is designed based on the Alford loop antenna structure in this paper, with the application background of WIFI and Bluetooth. The antenna is printed on a substrate which the radius only is 18ram and the relative perrnittivity is 2.65, small in size and light in weight. The designed antenna has good impedance characteristics and ommidirectionl characteristics in 2.4 GHz by using slot form and adding parasitic structure, with the roundness of only 0.9 dB. The proposed antenna can be used in, terminal communication of indoor and short distance.
