Abstract

This work presents the design for an antenna element that can be used in radio arrays for the monitoring and detecting of radio emissions from cosmic particles' interactions in the atmosphere. For these applications, the pattern stability over frequency is the primary design goal. The proposed antenna has a high gain over a relative bandwidth of 88%, a beamwidth of 2.13 steradians, a small group delay variation and a very stable radiation pattern across the frequency bandwidth of 110 to 190 MHz. It is dual polarized and has a simple mechanical structure which is easy and inexpensive to manufacture. The measurements show that the ground has insignificant impact on the overall radiation pattern.

摘要

这项工作展示了一种天线元件的设计，该元件可用于无线电阵列，以监测和探测大气中宇宙粒子相互作用产生的无线电辐射。对于这些应用，频率范围内的方向图稳定性是主要设计目标。所提出的天线在88%的相对带宽上具有高增益，波束宽度为2.13球面度，群延迟变化小，在110至190 MHz的频率带宽内辐射方向图非常稳定。它是双极化的，具有简单的机械结构，易于制造且成本低廉。测量结果表明，地面对整体辐射方向图的影响不大。
