Embodiment Construction

[0043] The present invention provides an implementation example of a device and method for designing a communication device and its antenna element. In communication devices, antenna elements can be used to reduce antenna size by utilizing the edge of the adjacent system ground plane to form part of the resonant path, and can successfully excite resonant modes for multi-frequency operation in response to different ground plane size variations .

[0044] Figure 1A It is a structural diagram of a communication device 1 according to an embodiment of the present invention. Such as Figure 1A As shown, the communication device 1 includes: a conductive ground plane 10 and an antenna element 12 .

[0045] An edge 101 of the conductor ground plane 10 (such as Figure 1A There is a notch 11 at the upper edge shown). The conductor ground plane 10 has at least a first edge 111 and a second edge 112 (such as Figure 1A As shown, for example but not limited to, the first edge 111 is a h...

Abstract

A communication device including a ground plane and an antenna element is provided. An edge of the ground plane is embedded with a notch, which has at least a first edge and a second edge. The antenna element, disposed at the notch, has at least a first operating frequency band and a second operating frequency band. The antenna element includes a first conductive portion and a second conductive portion. The first conductive portion has a starting terminal, electrically coupled to the first edge of the notch through a signal source, as a feeding terminal of the antenna element. A capacitive coupling portion is formed between an end terminal of the first conductive portion and the ground plane. The second conductive portion has a shorting terminal electrically coupled or connected to the second edge of the notch.

Description

technical field [0001] The invention relates to a communication device and a method for designing an antenna element thereof. Background technique [0002] Due to the advancement of integrated circuit and system-on-package (SOP) technology, the system ground area of ​​the internal communication circuit module of the mobile phone has been greatly reduced. Therefore, communication system application modules with different operating frequency bands can be integrated into a single mobile communication device. However, this will face the configuration of limited space in the mobile phone, as well as electromagnetic compatibility (EMC) between antenna elements or system modules for different applications. The system ground planes of different mobile communication devices often have different incomplete shapes. This is very unfavorable for the excitation of the lower resonance mode of the WWAN antenna, because the complete effective ground plane length helps to reduce the overall...
