AI Technical Summary
Technical Problem
In electronic devices, as screen ratio and thickness decrease, the design space for antenna modules becomes limited, making it challenging to cover more frequency bands within a limited space.
Method used
The system employs a combination structure of first, second, and third radiating branches. By setting first and second gaps and sharing the first upper frame point, it achieves coverage of low-frequency, mid-frequency, and high-frequency bands. Furthermore, it uses capacitor and inductor components to tune the frequency bands, thereby reducing the number of feed terminals and feed lines.
Benefits of technology
While reducing the space occupied by the antenna module, it can cover more frequency bands, reduce manufacturing costs, and improve antenna performance.

Abstract
This disclosure relates to an antenna module and an electronic device. The antenna module includes: a first radiating stub, a second radiating stub, a third radiating stub, and a feed terminal; the second radiating stub is disposed between the first and third radiating stubs; a first gap is formed between the second and first radiating stubs; a second gap is formed between the second and third radiating stubs; the feed terminal is connected to a first upper frame point of the second radiating stub and is used to output a feed signal to the second radiating stub, enabling the antenna module to operate in a first frequency band, a second frequency band, and a third frequency band; wherein the first frequency band includes a low-frequency band; the second frequency band includes a mid-frequency band; and the third frequency band includes a high-frequency band. Embodiments of this disclosure can cover more frequency bands while reducing the space occupied.
