Abstract
A wireless device having a CRLH structure incorporates a power combiner/divider and diplexer. In one embodiment, circuit parameters are selected to achieve impedance matching using a transmission line structure.
Claims20
A wireless device, comprising:
- a plurality of antenna elements having Composite Right/Left Hand (CRLH) structures;
- a power combiner/divider circuit coupled to each of the plurality of antenna elements, the power combiner/divider circuit having a plurality of feed paths, each having a diode;
- and
- a diplexer having a downstream end coupled to the power combiner/divider circuit, the diplexer having an upstream end operable to select between a plurality of paths for processing multiple frequency bands, a frequency band on one of the paths being different from a frequency band of a different path.
