一种无人机UHF高增益全向天线的设计
内容简介:本文提出了一种无人机UHF全向天线的实现方法,分析了其工作原理,给出了设计参数和实测结果。天线在225—512(MHz)频带内,电压驻波比小于3,真实增益在-0.5—2.5dBi范围内波动,不圆度小于3dB。实试结果表明,该天线具有良好的电性能特性,可以广泛应用在无人机及其它升空平台通信领域。
Abstract:The paper proposes e realization method of UAV UHF broadband omni - directional antenna, analyzes the working principleits, and gives the design parameters and measured results.In the 225-512 MHz band, the antenna voltage standing wave ratio of less than 3, the real gain fluctuations in the range of -0.5 to 2.5 dBi, roundness less than 3dB.The experiment results Show that the anten6a has ~oo~ electrical performance characteristics and can be widely used in the field of UAV and other launch platform communications.
