摘要
本文在W波段(75GHz-110GHz)设计了一个2x2对角喇叭阵列天线。其中对角喇叭天线单元的最大增益为24.5dB,为提高单元增益,在对角喇叭天线上设计了轴向的波纹槽,来拓展喇叭的有效长度,波纹喇叭的最大增益可达25.5dB。并将波纹对角喇叭组成辐射面约为41mm的2x2阵列天线,该阵列天线频带内最大增益可达31.6dB。并且基于最大功率传输(MMPTE)理论对阵列进行波束调控,最终实现夹角约为8°增益为29dB的双波束。
A 2x2 diagonal horn array antenna is designed in W-band(75 GHz-110 GHz).The maximum gain of a single diagonal horn can reach 24.5 dB,In order to improve the gain of Array element,an axial corrugated slot is designed on the diagonal horn antenna,the gain of corrugated antenna can reach 25.5 dB.The antennas are formed into a 2x2 array antenna finally,The maximum gain of the array in W-band can reach 31.6 dB,and it can realize the double beam with the angle of about 8°and the gain of 29 dB by the theory of MMPTE.
