Optimized conformal-to-meter antennas
A dual-dipole, multi-band conformal antenna for facilitating optimized wireless communications of a utility meter. The antenna includes an antenna backing, the backing adapted to conform to an inside surface of a utility meter and an antenna trace affixed to the antenna backing. The antenna trace is made of a conductive material and includes a symmetric low-band portion and an asymmetric high-band portion.
1. A dual-dipole, multi-band conformal antenna for facilitating optimized wireless communications of a utility meter, the antenna comprising:
an antenna backing, the backing adapted to conform to an inside surface of a utility meter; and
an antenna trace affixed to the antenna backing, the antenna trace comprising a conductive material and including:
a low-band portion for radiating in a low-band frequency range and having a left low-band arm and a right low-band arm, the left low-band arm being substantially the same as the right low-band arm such that the low-band portion is substantially symmetrical about a central axis of the antenna trace; and
a high-band portion for radiating in a high-band frequency range and having a left high-band arm having a left length and a right high-band arm having a right length, the left high-band arm and the right high-band arm being asymmetrical about the central axis of the antenna trace such that the right length of the right high-band arm is not substantially equal to the left length of the left high-band arm, the left length being the sum of lengths of all segments of the left high-band arm, and the right length being the sum of lengths of all segments of the right high-band arm;
wherein a left-side conductive area of the antenna trace is substantially equal to a right-side conductive area of the antenna trace.
2. The antenna of claim 1 , wherein the right low-band arm and the left low-band arm each consist of a single, rectangular trace segment.
3. The antenna of claim 1 , wherein the right high-band arm and the left high band arm each consist of a single, rectangular trace segment.
4. The antenna of claim 1 , wherein a vertical distance between the right high-band arm and the right low-band arm is substantially the same as a vertical distance between the left high-band arm and the left low-band arm.
5. The antenna of claim 1 , wherein the left high-band arm includes a first horizontal segment and a first vertical segment, and the right high band arm includes a first horizontal segment and a first vertical segment.
6. The antenna of claim 5 , wherein the first horizontal segment of the left high-band arm is transverse to the first vertical segment of the left high-band arm, and the first horizontal segment of the right high-band arm is transverse to the first vertical segment of the right high-band arm.
7. The antenna of claim 5 , wherein the left high-band arm further includes a second horizontal segment and a second vertical segment, and the right high-band arm includes a second horizontal segment and a second vertical segment.
