Abstract
An isolator assembly is configured to provide isolation in each of multiple non-overlapping frequency bands and includes a selection network to select one of the multiple non-overlapping frequency bands for an isolation operation. During the isolation operation, the isolator assembly prevents signal coupling between antennas that are positioned on opposite sides of the isolator assembly.
Claims20
Apparatus comprising:
- an isolator assembly that provides isolation between two antennas in multiple non-overlapping frequency bands, the isolator assembly including a resonating conductive isolation element and including a selection network configured to select one of the multiple non-overlapping frequency bands for an isolation operation, wherein the length of the conductive resonating isolation element measures less than ¼ of the wavelength of the frequency band selected for the isolation operation.
A method comprising:
- selectively resonating an isolator assembly including a resonating conductive isolation element in a frequency band, the isolator assembly including a selection network configured to select the frequency band from multiple non-overlapping frequency bands, wherein the length of the conductive resonating isolation element measures less than ¼ of the wavelength of the frequency band selected for the isolation operation.
An apparatus comprising:
- an isolator assembly that provides isolation between two antennas in multiple non-overlapping frequency bands, the isolator assembly including multiple interconnected conductive branches, each of the interconnected branches having a length measuring less than ¼ of the wavelength of one of the multiple non-overlapping frequency bands.
