Abstract: In accordance with one or more embodiments, a communication device includes a dielectric antenna having a longitudinal axis, a feed point and an aperture. A cable comprising a core is coupled to the feed point of the dielectric antenna. A transmitter, coupled to the cable, facilitates a transmission of first electromagnetic waves to the feed point of the dielectric antenna, the first electromagnetic waves guided by the core. The first electromagnetic waves propagate along the core without requiring an electrical return path, and the first electromagnetic waves generate free-space wireless signals from the aperture of the antenna in accordance with a hollow-boresight antenna beam pattern.

Abstract: In accordance with one or more embodiments, a communication device includes a dual-band antenna array configured to communicate RF signals in an RF band and to communicate MMW signals in a MMW frequency band with a remote device. At least one transceiver is configured to generate the RF signals conveying a command to the remote device to transmit probe signals in the MMW frequency band, to receive the probe signals via the dual-band antenna in the MMW frequency band, and is initialized with first antenna beam steering parameters to facilitate a first antenna beam of the dual-band antenna array for the operation in the MMW frequency band. A controller is configured to generate the first antenna beam steering parameters based on the probe signals and to generate the control signal to switch the dual-band antenna array to the operation in the MMW frequency band after transmission of the RF signals.
