Abstract
A dipole antenna (1) includes a first radiating trace (21) and a first grounding trace (31) respectively extending in substantially opposite directions, a second radiating trace (22) extending from an end of the first radiating trace in a direction which substantially perpendicular to the first radiating trace, and a second grounding trace (32) extending from an end of the first grounding trace in an opposite direction to the second radiating trace. The total length of the first and second radiating traces are ¼ operating wavelength of the dipole antenna.
Claims13
A dipole antenna comprising:
- a first radiating trace extending in a first direction;
- a first grounding trace aligned with the first radiating trace;
- a second radiating trace extending in a second direction from the first radiating trace;
- a second grounding trace extending from the first grounding trace opposite to and parallel to the second radiating trace;
- and
- a coaxial cable;
- wherein the total length of the first and second radiating traces are ¼ operating wavelength of the dipole antenna.
A dipole antenna comprising:
- a pair of matching traces parallel to each other with a predetermined distance;
- a first radiating trace and a first grounding trace oppositely extending from ends of the matching traces and aligned in a line;
- a second radiating trace extending from around an end of the first radiating trace in a first direction;
- a second grounding trace extending from an end of the second radiating trace in a second direction which is opposite to the first direction;
- wherein the second radiating trace is parallel to second grounding trace.
An antenna comprising:
- a substrate;
- a pair of dipole elements both disposed on the substrate and substantially having the same length;
- said pair of dipole elements comprising a first pair of dipole branches providing horizontal polarization, a second dipole branches providing perpendicular polarization.
