PATTERN-BANDWIDTH OPTIMIZATION OF THE SLEEVE MONOPOLE.
Abstract
The effect of varying the physical dimensions of the sleeve monopole upon its electrical characteristics is predicted theoretically by analogies with uniform radius cylindrical antennas and is verified experimentally. The theory of matching networks is sufficiently developed and it is shown that an impedance matching system can be located within the sleeve structure. It is also shown that the radiation pattern can be optimized over a given band and then, by using matching networks, the VSWR can be maintained below a certain level without altering the pattern. It is made evident that, subject to the Fano criteria, the impedance bandwidth can be optimized independently of the radiation pattern. A system is designed to satisfy typical specifications and the techniques used are clearly illustrated. (Author)
