Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing antenna structures in wireless communication devices are complex and occupy significant space, making it difficult to miniaturize these devices while effectively covering multiple frequency bands for wireless signal transmission and reception.
Innovation Solution
The proposed antenna structure utilizes a unique configuration with a side frame that includes specific gaps and grooves filled with insulating material, along with multiple signal sources and impedance circuits, to create multiple antenna modes (monopole, coupling-feed, and loop antennas) that can operate across LTE-A low, middle, and high frequency bands, as well as GPS and Wi-Fi frequencies, allowing for efficient signal transmission and reception without increasing the device's size.

Engineering Contradiction Analysis
1Adaptability or versatility
If traditional antenna structures are used to cover multiple frequency bands, then wireless signal transmission and reception capability is improved, but device size increases and structure becomes complicated
Solution Approach 1:
The side frame structure serves multiple antenna functions simultaneously. By configuring gaps and grooves in the side frame, it can operate as monopole antenna, coupling-feed antenna, and loop antenna across different frequency bands (LTE-A low, middle, high bands, GPS, Wi-Fi), eliminating the need for separate antenna structures for each function.
Solution Approach 2:
The patent combines multiple antenna modes into a single integrated side frame structure. The side frame with its specific gap and groove configurations integrates the functions of what would traditionally require separate monopole antennas, coupling-feed antennas, and loop antennas, thereby reducing overall device volume.

Data Source
AI summary
An antenna structure includes a housing, a first feed source, a first radiator, a second radiator, and a second feed source. The housing includes a first radiating portion. The first feed source feeds current to the first radiating portion and the first radiating portion activates a first mode to generate radiation signals in a first frequency band. The first radiator is positioned in the housing. The first radiating portion further couples the current to the first radiator and the first radiator activates a second mode to generate radiation signals in a second frequency band. The second radiator is positioned in a space formed by the first radiator. The second feed source feeds current to the second radiator and the second radiator activates a third mode to generate radiation signals in a third frequency band.
