Telescoping Antenna Assembly for Multi-Band Expandable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face challenges in accommodating multiple radio frequency (RF) communication bands and spatial diversity due to their compact form factor, especially with the introduction of millimeter wave (mmWave) technologies for 5G communications.
Innovation Solution
The implementation of a telescoping support structure within the communication device, which houses a configurable antenna assembly. This assembly includes antennas that move with the telescoping structure, allowing for the addition of lower RF communication bands when the device is in an extended arrangement, thereby supporting multi-band and multi-spatial communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a compact form factor is used for mobile communication devices, then mobility is enabled, but space for antennas is limited
Solution Approach 1:
The patent employs a telescoping support structure that dynamically changes the physical configuration of the device. The support structure can extend to provide additional space for antenna elements and retract to a compact form factor, allowing the antenna area to vary based on operational requirements while maintaining portability when not in use
2Reliability
If multiple antennas are placed at spaced-apart positions to support spatial diversity and MIMO operation, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The patent divides the antenna system into multiple independent antenna elements that can be individually positioned and configured. Each antenna element can be independently adjusted along the telescoping support structure, allowing for optimized spatial distribution to support MIMO and spatial diversity requirements while maintaining manageable system complexity through modular design
3Adaptability or versatility
If the telescoping support structure is extended to accommodate more antennas, then support for lower RF communication bands is added, but the compact form factor is compromised
Solution Approach 1:
The telescoping support structure provides a dynamic solution that allows the device to transition between compact and extended states. When extended, additional antenna elements are deployed to support lower RF communication bands. When retracted, the device returns to its compact form factor for portability, effectively providing adaptability across different operational scenarios

AI summary
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.
