Unitary antenna dipoles and related methods
View Patent ↗Unitary antenna dipole radiating elements are formed. Such elements include a base portion and a plurality of shaped arm portions unitarily formed on a side of the base portion. The antenna elements are configured to transmit and receive RF signals in a high frequency range.
1. A unitary high band dipole antenna element comprising:
a base portion comprising a shaped central portion and an end portion, the shaped central portion comprising a tubular inner portion that connects to the end portion, the end portion having a polygonal cross-sectional shape and configured to be secured within a receptacle of a chassis; and
a plurality of shaped arm portions unitarily formed on a side of the base portion opposite the end portion and configured to transmit and receive RF signals in a high frequency range, each arm portion comprising at least one slot, wherein the unitary high band dipole antenna element comprises a one-piece, unitary high band dipole antenna element.
2. The unitary high band dipole antenna element as in claim 1 wherein each arm portion includes a plurality of slots arranged in a fractal pattern.
3. The unitary high band dipole antenna element as in claim 1 wherein each arm portion includes a plurality of slots arranged in a Sierpinski carpet pattern.
4. The unitary high band dipole antenna element as in claim 1 wherein each arm portion is configured in a shape selected from the group consisting of a rectangular-shaped arm portion, triangle-shaped arm portion, star-shaped arm portion and fractal-shaped arm portion.
5. The unitary high band dipole antenna element as in claim 1 wherein two or more of the plurality of shaped arm portions have a same shape.
6. The unitary high band dipole antenna element of claim 1 , wherein the antenna element is configured to operate in a frequency range of 1700 MHz to 2700 MHz.
7. The unitary high band dipole antenna element of claim 1 wherein a first arm portion of the plurality of shaped arm portions includes a first connection opening having a first width and a second opposing arm portion including a second connection opening having a second, smaller width, and a third arm portion including a third connection opening having said first width and a fourth arm portion including a fourth connection opening having said second smaller width.
8. The unitary high band dipole antenna element as in claim 7 , wherein each of said first and third connection openings are configured to pass a corresponding one of two corresponding connecting cables therethrough, and each of said second and fourth connection opening are configured to receive a central conductor of a corresponding one of said two connecting cables.
9. A unitary high band dipole antenna element comprising:
a base portion comprising a shaped central portion and an end portion configured to be secured within a receptacle of a chassis, the shaped central portion comprising a tubular inner portion that connects to the end portion; and
a plurality of shaped arm portions unitarily formed on a side of the base portion opposite the end portion and configured to transmit and receive RF signals in a high frequency range, each arm portion comprising at least one slot, wherein the unitary high band dipole antenna element comprises a one-piece, unitary high band dipole antenna element.
10. The unitary high band dipole antenna element as in claim 9 wherein each arm portion includes a plurality of slots arranged in a fractal pattern.
11. The unitary high band dipole antenna element as in claim 9 wherein each arm portion includes a plurality of slots arranged in a Sierpinski carpet pattern.
12. The unitary high band dipole antenna element as in claim 9 wherein each arm portion is configured in a shape selected from the group consisting of a rectangular-shaped arm portion, triangle-shaped arm portion, star-shaped arm portion and fractal-shaped arm portion.
13. The unitary high band dipole antenna element as in claim 9 wherein two or more of the plurality of shaped arm portions have a same shape.
14. The unitary high band dipole antenna element as in claim 9 wherein the end portion has a polygonal cross-sectional shape.
15. The unitary high band dipole antenna element of claim 9 , wherein the antenna element is configured to operate in a frequency range of 1700 MHz to 2700 MHz.
16. The unitary high band dipole antenna element as defined in claim 9 wherein a first arm portion of the plurality of shaped arm portions includes a first connection opening having a first width and a second opposing arm portion including a second connection opening having a second, smaller width, and a third arm portion including a third connection opening having said first width and a fourth arm portion including a fourth connection opening having said second smaller width.
17. The unitary high band dipole antenna element as in claim 16 , wherein each of said first and third connection openings are configured to pass a corresponding one of two corresponding connecting cables therethrough, and each of said second and fourth connection opening are configured to receive a central conductor of a corresponding one of said two connecting cables.
