分析了柔性腔背槽天线腔内变形对其反射和辐射特性的影响,并与实测结果进行了比较。该天线是由导电纺织品制成的中空腔支撑的槽天线,并且可以沿球面弯曲。工作频率在2.4 GHz左右。分析了腔内有无变形时-10dB带宽和中心频率的频率特性。它们与平腔的情况进行了比较。对厚度增加和底面拉伸或收缩的空腔进行了建模,以模拟天线的特性。
Effects of the deformation in the cavity of a flexible cavity-backed slot antenna on its reflection and radiation characteristics have been analyzed and compared with the measured ones. The antenna is a slot antenna backed by a hollow cavity made of a conductive textile and can be bent along a spherical surface. It is designed for the operation frequency around 2.4 GHz. The frequency characteristics, -10dB bandwidth and the center frequency, are analyzed with and without deformation in the cavity. They are compared with a flat cavity case. Cavities with increased thickness and a stretched or shrunk bottom side face are modeled for the simulation of the antenna characteristics.
