A communication device and a method of making a communication device having an antenna assembly display and that supports multi-band communication. A multi-band antenna assembly of the communication device is incorporated into a telescoping support structure positionable between a compact arrangement and an extended arrangement to change an amount of a scrollable or rollable flexible display is presented. The antenna assembly includes at least one upper antenna positioned at an upper lateral side of a top end portion of the telescoping support portion and at least one lower antenna positioned at a lower lateral side of a bottom end portion of the telescoping support structure. The antenna assembly supports multi-band radio frequency (RF) communication in support of cellular and wireless protocols.

Multi-band antenna system for a communication device with expandable display form factor

A communication device provides a communication provide a multi-band antenna assembly incorporated into a telescoping support structure that is positionable between a compact arrangement and an extended arrangement. The antenna assembly includes at least one antenna having one antenna element that moves with an end portion of the telescoping support structure and another antenna element at an intermediate portion of the telescoping support structure that moves relative to the end portion. The two antenna elements are electromagnetically or conductively coupled to transceive radio frequency (RF) communication bands and add lower band(s) when the telescoping support structure is in the extended arrangement that are not supported when the telescoping support structure is in the compact arrangement. The communication device includes an antenna switching mechanism that configures the antenna assembly to support transceiving by transceiver(s) according to RF communication bands supported by a position of the telescoping support structure.
