摘要

本文提出了一种总尺寸为30×40×0.79mm3的新型微带馈电宽带低轮廓平面准单极天线。实际上，该天线是平面倒锥天线(PICA)的改进版。该天线由带两个狭缝的准三角形辐射单元和变形接地面组成，可提供约7.2GHz (3.8-11 GHz)的宽带。该频率范围包括无线局域网(WLAN)频段;因此，我们在辐射元件中使用u形槽来抑制5GHz-WLAN频段。模拟和测量结果显示，大的阻抗带宽和适当的辐射方向图是UWB应用所需要的。

Design and implementation of a new UWB microstrip antenna

This paper presents a new microstrip-fed wideband low-profile planar quasi-monopole antenna with total size of 30×40×0.79mm3. Practically, this antenna is a modified and improved version of Planar Inverted Cone Antenna (PICA). The proposed antenna consists of a quasi-triangular radiating element with two slits and a deformed ground plane, which provides wide bandwidth about 7.2GHz (3.8–11 GHz). This frequency range includes the Wireless Local Area Network (WLAN) band; hence we use a U-shape slot in radiating element to reject 5GHz-WLAN band. Simulated and measured results exhibit large impedance bandwidth and appropriate radiation pattern that is desired for UWB applications.
