现代国际遥测射频技术已进入微波波段(特别是S波段)。在常规箭弹兵器遥测系统中,要求地面站天线的灵活、机动、小巧轻便。本文介绍的螺旋馈源小抛物面天线即有高增益、宽频带和圆极化接收的特点。同时又符合以上要求,它将成为常规兵器微波遥测系统中的一种理想的实用天线。 Modern international telemetry radio frequency technology has entered the microwave band (especially the S band). In conventional missile-fired weapon telemetry systems, ground station antennas are required to be flexible, mobile, compact and lightweight. This article describes the spiral feed small parabolic antenna that has high gain, broadband and circular polarization receiver characteristics. At the same time meet the above requirements, it will become an ideal practical antenna in conventional weapons microwave telemetry system.
