Abstract

This paper proposes a single circular radiator with a multi-port (SRMP) antenna that can estimate the direction-of-arrival (DoA) in the azimuth and elevation directions. The proposed SRMP antenna is designed to minimize the size of the ultra-wideband system by using only one patch radiator. To verify the feasibility, the proposed antenna is fabricated, and the reflection coefficient and boresight gain are measured (-13.3 dB and 3.4 dBi at 8 GHz). Then, to observe the direction-finding performance, the DoA estimation results using the Bartlett beamformer are compared with the typical array. At all incident angles, a root-mean-square error of less than 1° is observed when the signal-to-noise ratio is higher than 6 dB.

用于测向应用的单圆形辐射器上多端口超宽带天线设计

本文提出了一种基于多端口天线的单圆形辐射器，可以在方位角和仰角方向上估计到达方向。所提出的SRMP天线通过仅使用一个贴片辐射体来减小超宽带系统的尺寸。为了验证该天线的可行性，制作了该天线，并测量了反射系数和轴视增益(-13.3 dB和3.4 dBi在8 GHz)。然后，将Bartlett波束形成器与典型阵列的DoA估计结果进行比较，观察其测向性能。在所有入射角下，当信噪比大于6 dB时，均方误差小于1°。
