Abstract

An appreciable increase in the broadcasting station network and a deterioration of the electromagnetic situation have resulted in the necessity to update the receiving antennas owing to the high requirements for broadband, directionality and various operational and consumer needs. Nowadays various constructions of folded-dipole antennas and circular antennas have been investigated in depth and used widely. However, the perspective of closed antenna improvement consists of a compromise between advantages and shortcoming of the boundary geometric version. This can be achieved by optimization of loop antenna shapes. In the present work, the approximate physico-mathematical model of an elliptical loop antenna with shunts is presented. This model is based on decomposition of the antenna current on equivalent in-phase and out-of-phase components. The analytical associations necessary for an evaluation of the radiation field and input impedance of the antenna were obtained.

椭圆环形天线的电磁模型

由于对宽带、方向性以及各种业务和消费者需要的高要求，广播电台网络的明显增加和电磁情况的恶化导致必须更新接收天线。目前，折叠偶极子天线和圆形天线的各种结构得到了深入的研究和广泛的应用。然而，从封闭天线改进的角度来看，边界几何版本的优点和缺点之间存在折衷。这可以通过优化环形天线的形状来实现。本文建立了带分流器的椭圆环形天线的近似物理数学模型。该模型基于天线电流在等效同相和非同相分量上的分解。得到了对天线的辐射场和输入阻抗进行评估所必需的分析关联。
