Abstract
Planar monopole antennas. A planar monopole antenna for communicating radio signals within a specific frequency range includes a substrate, a ground, a first sleeve, a second sleeve and a radiator. The radiator and the ground are formed on the substrate. The first and second sleeves project from a side of the ground in a first direction, wherein the first sleeve has a first length, and the second sleeve has a second length in the first direction. The side of the ground defines a third length. The radiator has a fourth length in the first direction, substantially equal to the sum of the first, second, and third lengths.
Claims20
A planar monopole antenna for communicating a radio signal, comprising:
- a substrate;
- a ground;
- a first sleeve, formed on the substrate and electrically connected to the ground, wherein the first sleeve projects from a side of the ground in a first direction with a first length;
- a second sleeve, formed on the substrate and electrically connected to the ground, wherein the first sleeve projects from the side of the ground in the first direction with a second length, and the side of the ground defines a third length from the first sleeve to the second sleeve;
- a radiator, formed on the substrate and situated between the first and second sleeves, wherein the radiator has a fourth length in the first direction, substantially equal to the sum of the first, second, and third lengths;
- and
- a cable, connecting the radiator for communicating the radio signal.
