Patent ID: 7348930

Claim:
A radio transceiver, comprising: a first radio and a second radio that transmit and receive using a first frequency and a second frequency respectively; a first antenna and a second antenna having a first coverage area and a second coverage area respectively, the first antenna and the second antenna couple to the first radio and the second radio respectively; a first antenna spacer and a second antenna spacer mount to the first antenna and the second antenna respectively; and a shield having a size, a first side, and a second side; wherein: the first antenna spacer mounts to the first side thereby positioning the first antenna a first distance from the first side; the second antenna spacer mounts to the second side thereby positioning the second antenna a second distance from the second side; a distance between the first antenna and the second antenna comprises at most two times the wavelength of at least one of the first frequency and the second frequency; and the first coverage area overlaps the second coverage area thereby forming at least one virtual sector.
