Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an antenna array of various antenna configurations is used to capture a greater portion of the LTE spectrum, then frequency band coverage is improved, but device size and space requirements increase making it impractical for small devices
Solution Approach 1:
The patent combines multiple antenna elements (first antenna element for low band, second antenna element for high band, and third antenna element for high band) into a single integrated antenna assembly. This merging allows the device to support multiple LTE frequency bands (600 MHz-700 MHz low band and 2.7 GHz-6.0 GHz high band) while maintaining a compact form factor suitable for small devices, resolving the contradiction between frequency band coverage and device size.
2Volume of moving object
If a single antenna configuration is used to reduce device size, then device compactness is improved, but frequency bandwidth is limited and cannot cover the full LTE spectrum
Solution Approach 1:
The antenna assembly is designed with multi-functionality to perform multiple roles within a single compact structure. The first antenna element provides low band resonance (600 MHz-700 MHz), while the second and third antenna elements provide high band resonance (2.7 GHz-6.0 GHz). This universal design allows a single antenna assembly to cover the entire LTE spectrum range, achieving both compactness and broad frequency bandwidth coverage.
Solution Approach 2:
The patent utilizes three-dimensional spatial arrangement of antenna elements to achieve multi-band coverage in a compact volume. The antenna elements are positioned at different orientations and heights (with spacing of 0.05-0.15 inches between elements), creating a three-dimensional structure that maximizes electromagnetic resonance across different frequency bands while maintaining a small overall device footprint.
3Reliability
If antennas are configured to resonate within a dedicated frequency bandwidth to avoid interference, then communication reliability is improved, but frequency channel competition occurs as more devices use the same bandwidth
Solution Approach 1:
The antenna assembly is designed with adjustable resonance parameters through its multi-element structure. By configuring the first antenna element with specific dimensions for low band resonance and the second and third elements with different dimensions for high band resonance, the system can selectively operate across different frequency parameters. This allows devices to access multiple frequency channels (600 MHz-700 MHz and 2.7 GHz-6.0 GHz bands), reducing frequency channel competition while maintaining communication reliability through dedicated resonance configurations.

AI summary
A multi-band antenna has a feed point, a grounding location, a first portion for low band operation, a second portion for low band operation, and one or more portions for high band operation. The ground reference of the feed point for the multi-band antenna is connected to a separate object that may provide a base for the multi-band antenna. The feed point of the multi-band antenna may be spaced above the base and have a space between the feed point and a location for the ground point. The low band portion has multiple resonances that are often odd multiples of the lowest resonant response. The portions that resonant most dominantly in the high band often have multiple resonances that are even multiples of the lowest high band resonance. The multi-band antenna has resonances spaced closely enough to appear to be a wide band antenna above the fundamental high band resonance.
