Abstract:
1. An antenna comprising: a substrate with a metal layer; a bowtie-shaped dipole antenna formed in the metal layer with two triangle elements with a gap between the two triangle elements, and wherein the bowtie-shaped dipole antenna is tuned to a lower portion of the UHF band; a pair of transmission lines formed in the metal extending from near the gap; and at least one pair of tuning stubs formed in the metal and extending from the transmission lines, wherein each of the at least one pair of tuning stubs is tuned to a frequency band that is different than the lower portion of the UHF band; wherein the triangle elements are generally isosceles triangles; wherein a first side and a second side are equal length sides of the isosceles triangles, wherein isosceles triangle points are formed where first sides and the seconds side touch, wherein the isosceles triangle points lie on a centerline adjacent each other but separated from each other by the gap, wherein third sides of the isosceles triangles that are not equal to any other isosceles triangles sides cross the centerline remote from and non-adjacent each other so that the centerline bisects the third sides; wherein a perpendicular line passes through the gap perpendicular to the centerline, wherein the at least one pair of tuning stubs includes a pair of upper UHF tuning stubs that are generally elongated and rectangular in shape with short segments and long segments, wherein the short segments are generally parallel to the perpendicular line and the long segments are generally parallel to the centerline; wherein the at least one pair of tuning stubs includes a pair of VHF tuning stubs at least partially between the upper UHF tuning stubs and the triangle elements; and wherein each of the pair of VHF tuning stubs further comprises: first elongated sections extending from the transmission lines, between the upper UHF tuning stubs and the triangle elements, and generally parallel to the upper UHF tuning stubs; jog sections; and elongated end sections pointing in a direction generally parallel to an elongated direction of the upper UHF tuning stubs, wherein the jog sections are positioned between the first elongated sections and the elongated end sections to jog the VHF tuning stubs around ends of the upper UHF tuning stubs.
