| Abstract: | Two different wide-slot antennas for UWB applications are presented in this paper：a CBCPW-fed wide-slot antenna and a stripline-fed wide-slot antenna. The measured results show that these two antennas can achieve very broad impedance band. The characteristic parameters are also given. The gain and radiation of the two antennas are compared to each other. Then the far-zone propagation of impulse radiation through these two antennas has been studied and we make a conclusion of the effects of different structures, which is significant for future design. |
