Abstract
The present subject matter relates to antenna systems, devices, and methods that provide efficient coverage of low frequency bands (e.g., 700 MHz-bands and 600 MHz-bands) for the new generations of mobile communication. For example, a dual-resonant radiating system can include a ground plane, a radiating coupler spaced apart from but in communication with the ground plane, and a ground plane extension in communication with the ground plane. In this arrangement, one or both of the radiating coupler and the ground plane extension are tunable to tune a dual-resonance frequency response.

A dual-resonant radiating system comprising:
- a ground plane;
- a radiating coupler spaced apart from but in communication with the ground plane;
- and
- a ground plane extension in communication with the ground plane;
- wherein one or both of the radiating coupler and the ground plane extension are tunable to tune a dual-resonance frequency response.
A dual-resonant radiating system comprising:
- a ground plane;
- a radiating coupler spaced apart from but in communication with the ground plane;
- a first tunable element connected between a coupler connection of the radiating coupler to the ground plane and a ground;
- a series tunable capacitor connected between the coupler connection of the radiating coupler to the ground plane and a feed node;
- a ground plane extension in communication with the ground plane;
- and
- a second tunable element connected to the ground plane extension;
- wherein the first tunable element and the series tunable capacitor are configured to tune a resonant frequency of the radiating coupler;
- and
- wherein the second tunable element is configured to tune a resonant frequency of the ground plane.
A method for operating an antenna, the method comprising:
- tuning a first resonant frequency of a radiating coupler that is spaced apart from but in communication with a ground plane;
- and
- tuning a second resonant frequency of a combination of the ground plane and a ground plane extension that is in communication with the ground plane;
- wherein the first resonant frequency and the second resonant frequency add constructively to form a dual-resonance frequency response.
