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.
Claims19
A dual-resonant radiating system comprising:
- a ground plane;
- a radiating coupler spaced apart from but in communication with the ground plane, wherein the radiating coupler is tunable to tune an antenna resonance;
- and
- a ground plane extension in communication with the ground plane and tunable to tune a ground plane resonance;
- wherein the radiating coupler and the ground plane extension are tunable to independently tune the antenna resonance and the ground plane resonance to achieve a constructively-additive dual-resonance frequency response.
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 tuning the second resonant frequency is independent from tuning the first resonant frequency;
- wherein the first resonant frequency and the second resonant frequency add constructively to form a dual-resonance frequency response.
