摘要

提出了一种用于超宽带(UWB)应用的心形单极天线。该结构是在FR-4衬底上设计一个简单的心形贴片，由50欧姆微带线馈电。为了改善天线的匹配性能和宽带性能，对天线的接地面进行了改进。对位于地平面区域的半圆槽进行了参数化研究。S11< -10dB的测量频率范围为2.7- 26ghz。天线总尺寸为48×40mm(宽×长)。

Heart shaped monopole antenna with defected ground plane for UWB applications

In this paper a monopole antenna with shape of heart for Ultra Wide Band (UWB) applications is proposed. The structure is a simple patch with shape of heart designed on FR-4 substrate and fed by a 50 Ohms microstrip line. The ground plane of the antenna has been modified including several defects to improve its behavior in matching and wideband. A parametric study has been performed to the semicircular slots located in the ground plane area. The frequency range measured for S11<;-10dB was from 2.7-26 GHz. The total dimensions of the antenna are 48×40mm (W × L).
