Dual band, low profile omnidirectional antenna
First Claim
1. A low-profile dual-band antenna, comprising:
- a ground plane;
an “
E”
-shaped metal plate that is located a first distance from said ground plane and that includes first and second outer extensions and an inner extension of said metal plate;
a feed tab that connects said inner extension and said ground plane; and
a shorting tab that connects said inner extension and said ground plane;
wherein said low-profile dual-band antenna communicates first radio frequency (RF) signals in a first RF band and second RF signals in a second RF band.

Abstract
A low-profile dual-band antenna includes a ground plane. An “E”-shaped metal plate is located a first distance from the ground plane and includes first and second outer extensions and an inner extension of the metal plate. A feed tab connects the inner extension and the ground plane. A shorting tab connects the inner extension and the ground plane. The low-profile dual-band antenna communicates first radio frequency (RF) signals in a first RF band and second RF signals in a second RF band. The first RF signals and the second RF signals are vertical polarized signals. The low-profile dual-band antenna produces a radiation pattern that is omnidirectional in the azimuth plane and vertically polarized in a horizontal plane when communicating the first RF signals and the second RF signals. The first RF band and the second RF band can be independently tuned.

12. A method for producing a low-profile dual-band antenna, comprising:
-
forming first and second parallel slots in a metal plate, wherein said first and second parallel slots are symmetrically disposed about a center point of said metal plate and produce first and second outer extensions and an inner extension of said metal plate; providing a ground plane; connecting a first end of a feed tab to said inner extension and a second end of said feed tab to said ground plane; connecting a first end of a shorting tab to said inner extension and a second end of said shorting tab to said ground plane; wherein said low-profile dual-band antenna communicates first radio frequency (RF) signals in a first RF band and second RF signals in a second RF band. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
