The embodiment of the invention relates to an airborne antenna and an aircraft. According to the method, a base, an antenna oscillator, a broadband matching network and an antenna housing are included, an antenna cavity is formed by the antenna housing and the base, the antenna oscillator and the broadband matching network are located in the antenna cavity, and the antenna oscillator is connected with a radio frequency connector on equipment for installing the airborne antenna through the broadband matching network; the quality factor of the broadband matching network is smaller than a preset threshold value, and the broadband matching network is used for expanding the working frequency band of the airborne antenna while matching the output impedance of the airborne antenna; wherein the preset threshold value is determined according to the ratio of the working frequency band of the antenna after widening to the working frequency band of the antenna before widening, and the ratio is greater than 5. According to the airborne antenna, the working frequency band of the airborne antenna can be widened, the number of the airborne antennas installed on an airplane can be reduced, and the load of the airplane is reduced.

    本申请实施例涉及一种机载天线以及飞机。所述方法包括:底座、天线振子、宽带匹配网络和天线罩,天线罩与底座形成天线腔体,天线振子和宽带匹配网络位于天线腔体内部,且天线振子通过宽带匹配网络与安装机载天线的设备上的射频连接器连接;宽带匹配网络的品质因数小于预设阈值,用于在匹配机载天线输出阻抗的同时,拓宽机载天线的工作频段;其中,预设阈值为根据拓宽后的天线工作频段与拓宽前的天线工作频段的比值确定的,比值大于5。该机载天线能够拓宽机载天线的工作频段,可以减少飞机上安装的机载天线的数量,减轻飞机的负重。
