Abstract
An antenna system comprises a transmission member and an antenna at a distal end of the transmission member. The antenna includes a first conductive arm, an insulator extending around the first conductive arm, and a second conductive arm wound around at least a first portion of the insulator to form a second conductive arm coil. A property of the insulator varies along an insulator longitudinal axis of the insulator. The insulator includes a set of formed patterns along at least a portion of the insulator longitudinal axis.
Claims20
An antenna system comprising:
- a transmission member;
- and
- an antenna at a distal end of the transmission member, the antenna including a first conductive arm, an insulator extending around the first conductive arm, and a second conductive arm wound around at least a first portion of the insulator to form a second conductive arm coil, wherein a property of the insulator varies along an insulator longitudinal axis, and wherein the insulator includes a set of formed patterns along at least a portion of the insulator longitudinal axis.
The antenna system of claim wherein the set of formed patterns includes at least one of laser-cut slots extending through at least a second portion of the insulator, H-pattern cuts extending through at least a third portion of the insulator, or curved pattern slots.
An antenna system comprising:
- a transmission member;
- and
- an antenna at a distal end of the transmission member, the antenna including a first conductive arm, an insulator extending around the first conductive arm, and a second conductive arm wound around at least a first portion of the insulator to form a second conductive arm coil, wherein a property of the insulator varies along an insulator longitudinal axis, wherein the insulator includes a first section comprised of a first material and a second section comprised of a second material, and wherein the first section and the second section are positioned at different locations along the insulator longitudinal axis.
An antenna system comprising:
- a transmission member;
- and
- an antenna at a distal end of the transmission member, the antenna including
- a first conductive arm,
- an insulator extending around the first conductive arm, and
- a second conductive arm wound around at least a portion of the insulator, the second conductive arm forming a second conductive arm coil extending across a transition between the transmission member and the insulator or between the insulator and a distal tip member coupled to a distal end of the insulator, wherein a property of the second conductive arm coil is different at the transition than at the portion of the insulator.
