Mountable antenna elements for dual band antenna
First Claim
1. A self-standing mountable antenna that transmits a radio frequency signal, the antenna comprising:
- a top surface in a first plane, the top surface formed from a single sheet of material;
a radio frequency feed extending from the top surface and coupled to a radio frequency source;
a plurality of legs extending from the top surface and coupled to a ground plane; and
a first bendable impedance matching element extending from the top surface towards the ground plane, wherein the radio frequency feed, the legs, and the first bendable impedance matching element are all formed from the same single sheet of material as the top surface and are each bent downwardly therefrom towards the ground plane, and wherein the first bendable impedance matching element forms a capacitance with the ground plane that is determined by an adjustable spatial distance between a bottom edge of the first bendable impedance matching element and the ground plane, the spatial distance being adjustable by bending the first bendable impedance matching element with respect to the top surface.

Abstract
A mountable antenna element is constructed as an object from a single piece of material and can be configured to transmit and receive RF signals, achieve optimized impedance values, and operate in a concurrent dual-band system. The mountable antenna element may have one or more legs, an RF signal feed, and one or impedance matching elements. The legs and RF signal feed can be coupled to a circuit board. The impedance matching elements can be utilized to create a capacitance with a portion of the circuit board and thereby optimize impedance of the antenna element at a desired operating frequency. The mountable antenna includes features that enable it for use in concurrent dual band operation with the wireless device. Because the mountable antenna element can be installed without needing additional circuitry for matching impedance and can be constructed from a single piece of material, the antenna element provides for more efficient manufacturing.
