Title:
DECADE BAND TAPERED SLOT ANTENNA, AND METHODS OF MAKING AND CONFIGURING SAME
Document Type and Number:
WIPO Patent Application WO2003021715
Kind Code:
A3
Abstract:
An antenna apparatus (10) includes an antenna element (12, 412, 512) that has conductive material with a recess therein. The recess includes a balun hole (36, 536), and a tapered slot (37, 537) communicating at its narrow end with the balun hole. The balun hole is approximately rectangular, has a peripheral edge defined by conductive material, and contains air. The tapered slot has a shape which is optimized as a function of factors that include the balun hole design. Each slot edge follows a predetermined curve other than a first-order exponential curve.
