5 GHz to 70 GHz Double Ridged Broadband Waveguide Horn Antenna, V-Female Connector (1.85mm)
矩形口径喇叭天线(Rectangular Horn Antenna)是一种常见的定向和高增益天线设计,主要用于无线通信系统中,特别是在雷达、卫星通信以及射频测试设备中。优化这种天线是为了提高其性能指标,如方向性、效率和带宽。 1. **尺寸优化**:天线的设计参数,如宽度、长度和深度,会影响其辐射模式。通过计算和模拟软件,工程师会确定最佳的尺寸比例,使得在所需频率范围内,天线的主瓣保持稳定,副瓣衰减良好。 2. **阻抗匹配**:为了最大限度地传输信号能量,天线需要与馈电网络有良好的匹配。这可能涉及到改变喇叭内部结构或添加匹配负载,以使输入阻抗接近理想值(通常为50欧姆)。 3. **表面粗糙度处理**:天线的表面平滑度影响电磁波反射。
