AI Technical Summary

Technical Problem

The challenge is to design a compact antenna component that can support multiple frequency bands in limited space, particularly for 5G communication systems, where the increasing number of antennas and frequency segments require efficient use of available space without compromising performance.

Method used

The antenna component includes two distinct units: one with a radiating branch and a feed source that operates in two modes for the first frequency band, and another with a radiating branch, parasitic branch, and feed source that operates in three modes for the second frequency band, utilizing specific feed points and coupling mechanisms to enhance radiation performance across both bands.

Benefits of technology

This configuration effectively improves radiation performance for both frequency bands by ensuring the antenna units resonate at multiple frequencies, enabling efficient signal reception and transmission across a wider frequency range within the limited space constraints.

Abstract

The embodiment of the invention provides an antenna assembly. The antenna assembly comprises a first antenna unit and a second antenna unit. The first antenna unit comprises a first radiation branch knot and a first feed source, the first radiation branch knot comprises a first feeding point, the first feeding point is connected with the first feed source, and the first feed source is used for exciting the first radiation branch knot to generate two working modes working in a first frequency band. The second antenna unit comprises a second radiation branch knot, a parasitic branch knot and a second feed source, the second radiation branch knot comprises a second feeding point, the second feeding point is connected with the second feed source, and the parasitic branch knot is coupled with the second radiation branch knot; and the second feed source excites the second radiation branch knot through the second feed point, and excites the parasitic branch knot through coupling of the second radiation branch knot so as to generate three working modes working in a second frequency band. The invention further provides electronic equipment. According to the invention, the requirement of multiple antenna frequency bands can be met in a limited clearance area.
