Hewlett-Packard Development Company, L.P. - Houston TX
International Classification:
H01Q 21/28
H01Q 1/52
H01Q 1/24
Abstract:
Example implementations relate to separate antennae. In one example, separate antennae can include an antenna system having a first antenna to receive and transmit signals in a first frequency band, a second antenna to receive signals in a second frequency band and transmit and receive signals in a third frequency band, and a third antenna to receive signals in a fourth frequency band, where each of the first antenna, the second antenna, and the third antenna are physically separate and distinct
