摘要

本文介绍了三种不同的椭圆槽超宽带(UWB)天线。这些天线是用标准的印刷电路板(PCB)工艺提出和设计的，以适合与射频/微波电路集成。第一种设计采用半圆形环形散热器元件，另一种设计采用半椭圆环形散热器元件。散热器的形状为新月形，用于第三种设计。计算得到的天线阻抗带宽范围为2.5GHz至14GHz以上，反射系数(S11)小于−10dB。此外，所有设计在其整个感兴趣的频段内都具有相对稳定的辐射模式。

Analysis and design of UWB elliptical slot antennas

In this paper, three different elliptical slot ultrawideband (UWB) antennas are presented. These antennas are proposed and designed with a standard printed circuit board (PCB) process to be suitable for integration with radio-frequency/microwave circuitry. The first design is composed of half circular ring radiator element while the other design uses half elliptical ring shaped radiator. The shape of the radiator is crescent shaped for the third design. The calculated impedance bandwidth of proposed antenna designs ranges from 2.5GHz to beyond 14GHz for reflection coefficient (S11) less than −10dB. Also, all designs have relatively stable radiation patterns over their whole frequency band of interest.
