摘要
In this article, a cavity-backed bowtie antenna (CBBA) is proposed and investigated.Compared with the conventional CBBA, parasitic stubs are added to the open-end of the Bowtie. The parasitic stubs provide capacitive loading and allows the design to exhibit a low profile over a relatively wide bandwidth. Parametric studies are performed to optimize the antenna performance. For verification, a prototype was fabricated and measured. Experimental results show the VSWR of less than 2.0:1 from 1.97 to 8.5 GHz. However, the radiation pattern degrades beyond 7.5 GHz. This limits the operating bandwidth to about 117%. The height of the prototype is 15 mm which is only 0.1 λmax (λmax is the wavelength at the lowest operating frequency) © 2013 Wiley Periodicals, Inc.
