Abstract
A dielectric loaded sleeve monopole antenna has a dielectric loading within the sleeve enables stable impedance in a dynamic operating environment. The use of a dielectric filling in the sleeve portion of the antenna enables tight control of the input impedance over frequency establishing stable broadband operation in challenging operating environments. The effective dielectric constant inside the sleeve of the antenna is designed to exhibit spatial variability. As a result, the sleeve essentially acts as an impedance transformer enhancing control over the input impedance to the antenna. The spatial variability in the dielectric filling may be realized as arrangements of single or multiple dielectric materials machined to synthesize the desired effective dielectric properties.
