Investigation of Broadband Microstrip Antenna Structures for Application in Monolithic Millimeter Wave Arrays
Abstract
Our studies have shown the development of several ways of accurately yet efficiently modelling the behavior of closely spaced microstrip antenna elements. The accuracy has been verified by comparison with 'brute force' numerical procedures, and thus suggests that wideband microstrip antennas should be designable with much less difficulty than previously believed. Further, both experimental and numerical evidence has been obtained for the proposition that wider bandwidth, and even lower frequency operation of a microstrip patch antenna element can be achieved by arranging many closely coupled narrow strip dipoles together in an appropriate way. We are far from a complete understanding of these effects; especially there has been no study of the frequency dependence of the radiation properties of these new elements. Design and optimization of them is also in a very primitive stage, as accurate modeling of their properties requires numerically intensive methods at this time. Questions of this nature deserve more investigation.
