Embodiment Construction

[0057] The following disclosure provides many different embodiments, or examples, for implementing the various features of the application. Specific examples of components and configurations are described below to simplify the disclosure of the present application. Of course, these are examples only and are not intended to limit the application. For example, the following description of forming a first feature on or over a second feature may include embodiments in which first and second features are formed in direct contact, and may also include embodiments in which other features are formed between the first and second features. , so the first and second features are not in direct contact. Additionally, the application may repeat element symbols and / or letters in different instances. This repetition is for simplicity and clarity and does not dictate the relationship between the different embodiments and / or architectures discussed.

[0058]Furthermore, the application can u...

Abstract

The invention provides an electronic device. The electronic device comprises a metal housing, a slot antenna, a first dielectric substance and a second dielectric substance. The slot antenna is arranged in the metal housing and generates a signal. The dielectric constant of the second dielectric substance is higher than the dielectric constant of the first dielectric substance. The slot antenna comprises a conductive member. The conductive member is configured to define a slot closed at two ends, the first dielectric substance and the second dielectric substance are arranged in the slot, wherein the slot has a length, the length and the first dielectric substance together determine that a high frequency band of the signal is in accordance with a high frequency band of the WIFI protocol, and the length and the first dielectric substance together determine that a low frequency band of the signal is higher than a low frequency band of the WIFI protocol. The second dielectric substance reduces the low frequency band of the signal to the range of the low frequency band of the WIFI protocol. By using the second dielectric substance, the slot antenna can generate dual-band WIFI signals even if the slot antenna is located in the metal housing.

Description

technical field [0001] The present application relates to an electronic device, in particular to an electronic device with a metal casing. Background technique [0002] Currently, using a metal shell as a product shell is very popular in consumer electronic products, such as iPHONE series or iMac computers. Because the metal shell can improve the strength of the product and provide users with a good touch. However, if there are metal substances around the antenna, the performance of the antenna on radio frequency will be reduced. In more detail, traditional antennas, such as monopole antennas, inverted-F antennas (IFA) and planer-inverted-F antennas (PIFA), cannot Work. The full metal enclosure condition means that the antenna is mostly surrounded by a metal enclosure. Contents of the invention [0003] Embodiments of the present application provide an electronic device. The electronic device includes a metal casing, a slot antenna, a first dielectric substance and a ...
