Title:
WIDE BAND MICROSTRIP ANTENNA AND MANUFACTURE OF THE SAME
Document Type and Number:
Japanese Patent JPS63189002
Kind Code:
A
Abstract:
A three resonator capacitively coupled microstrip antenna structure includes an inverted stacked array of elements with a lowermost driven element (104) directly connected to a transmission line connector (18), and passive elements (106, 108) stacked above the driven element and separated from the driven element and from one another by dielectric layers (112, 114). The dimensions, spacings and quality factors of the elements are chosen so that at least one, and possibly two elements are resonant at any given frequency within a desired frequency operating range. The resulting antenna structure offers very broad bandwidth at relatively low VSWR in a compact, rugged package. The manner in which parameters of the stacked antenna structure are specified to achieve desired VSWR bandwidth and radiation efficiency is also described.
