Portable computer and dipole antenna thereof

Abstract

The invention relates to a portable computer and a dipole antenna thereof. A dipole antenna, comprising a signal wire, a grounding wire, a substrate, a first radiation element and a second radiation element. The substrate comprises a first surface and a second surface; the first radiation element is arranged on the first surface and is electrically connected to the signal wire, the first radiation element comprises a first connection part and a first extension part, the extension part comprises a first transition part, the first extension part is divided into a first section and a second section by means of the first transition part, and the first section part is connected to the first connection part. The second radiation element is arranged on the second surface and is electrically connected to the grounding wire, and the second radiation element comprises a second connection part.

Description

technical field [0001] The present invention relates to a dipole antenna, in particular to a small dipole antenna. Background technique [0002] refer to Figure 1a , which shows a conventional dipole antenna 1 including a first arm 10 , a second arm 20 , a signal line 31 and a ground line 32 . The signal wire 31 is electrically connected to the first arm 10 , and the ground wire 32 is electrically connected to the second arm 20 . The dipole antenna 1 is used for transmitting a wireless signal, and the wireless signal has a wavelength λ. [0003] In the conventional technology, the lengths of the first arm 10 and the second arm 20 are both λ / 4, therefore, the volume of the traditional dipole antenna 1 is large. refer to Figure 1b , the traditional dipole antenna also has a casing 40 , and the casing 40 covers the first arm 10 , the second arm 20 , the signal line 31 and the ground line 32 . When the traditional dipole antenna 1 is arranged on the upper edge of a portabl...

AI Technical Summary

Problems solved by technology

When the traditional dipole antenna 1 is arranged on the upper edge of a portable computer (for example, a notebook computer), it will affect the appearance of the portable computer

However, when the traditional dipole antenna 1 is arranged on the side of the portable computer, since the electric field is blocked by components such as circuit boards, it cannot provide good signal transmission effect.
