Abstract:
1. An antenna, comprising: a bowtie dipole disposed on a first side of a substrate, the bowtie dipole comprising first and second opposed conductive elements, wherein each of the first and second opposed elements of the bowtie dipole is defined by a triangular pattern; and a feed structure disposed on a second side of the substrate, the feed structure comprising first and second opposed feed elements having a length, width and height, wherein the width of the first feed element is tapered from a first width at a first end of the first feed element to a second width at a second end of the first feed element, the width of the second feed element is tapered from a third width at a first end of the second feed element to a fourth width at the second end of the second feed element and wherein the first and second opposed feed elements are coplanar and have an intersection area at their respective first ends, and further wherein the length of the second feed element is longer than a length of each of the first and second opposed elements of the bowtie dipole, and wherein the feed structure is disposed on the substrate such that the first element of the feed structure overlaps with the first element of the bowtie dipole and the second feed element overlaps with both the first and second elements of the bowtie dipole, the second feed element being directly electrically connected to a center conductor of a transmission line; wherein the length of the second feed element is chosen so as to impedance match the first element of the bowtie dipole with the transmission line for feeding the antenna.
