Abstract

A 3-D beam scanning antenna array design is proposed that gives a whole 3-D spherical coverage and also suitable for various radar and body-worn devices in the Body Area Networks applications. The Array Factor (AF) of the proposed antenna is derived and its various parameters like directivity, Half Power Beam Width (HPBW) and Side Lobe Level (SLL) are calculated by varying the size of the proposed antenna array. Simulations were carried out in MATLAB 2012b. The radiators are considered isotropic and hence mutual coupling effects are ignored. The proposed array shows a considerable improvement against the existing cylindrical and coaxial cylindrical arrays in terms of 3-D scanning, size, directivity, HPBW and SLL.

摘要

提出了一种三维波束扫描天线阵列设计，该设计可实现整个三维球面覆盖，并且适用于体域网应用中的各种雷达和可穿戴设备。推导了所提天线的阵列因子，并通过改变所提天线阵列的尺寸来计算其诸如方向性、半功率波束宽度（HPBW）和旁瓣电平（SLL）等各种参数。在MATLAB 2012b中进行了仿真。假设辐射器为各向同性，因此忽略了互耦效应。在所提阵列的三维扫描、尺寸、方向性、HPBW和SLL方面，与现有的圆柱形和同轴圆柱形阵列相比有显著改进。
