摘要
本文在矩形微带贴片天线的基础上，通过在贴片上开两条对称的缝隙而得到E型贴片天线。经过仿真优化计算出E型贴片天线的尺寸，确定了最终方案模型，得到了方向图、回波损耗等参数。设计的天线工作频率为1．88GHz到2．4GHz，带宽达25．2％，谐振频率的增益达9．38dB。该天线拥有结构简单、体积小、宽频带特点，具有很好的实际应用价值。
On a basis of the traditional microstrip patch antenna, E-shape patch antenna is obtained by loading two symmetric slots one another. The size of the E-shape patch antenna is calculated and the physical model is determined, from which such the parameters as the radiation pattern and echo loss are presented. The designed antenna can operate at the frequency of 1.88GHz to 2.4GHz, the frequency bandwidth is 25.2%, and the gain of the resonant frequency is up to 9.4dB. The antenna has advantages with simple structure, small size, and broadband and is applicable for engineering.
