Problems solved by technology

The disadvantage of this method is that it will reduce the efficiency of the antenna and affect the radiation characteristics of the antenna
In addition, if the antenna operates in the LTE700 frequency band (704MHz~787MHz), the isolation element must resonate at about 700MHz, which will greatly increase the size of the overall antenna system, thereby increasing the difficulty of overall design integration

Embodiment Construction

[0041] In order to make the above-mentioned objectives, features and advantages of the present invention more obvious and understandable, specific embodiments of the present invention are specifically listed below, with accompanying drawings, and detailed descriptions are as follows.

[0042] figure 1 It is a schematic diagram showing the communication device 100 according to the first embodiment of the present invention. In the first embodiment, the communication device 100 includes: a first antenna 11, a second antenna 12, and a support plate 13. The first antenna 11 and the second antenna 12 form an antenna system. The supporting plate 13 includes a conductive plate 14 and a non-conductive plate 15. The conductive plate 14 has a first edge 141 and a second edge 142. The second edge 142 is the opposite side of the first edge 141, and the second edge 142 is adjacent to the non-conductive plate 15. The first antenna 11 has a feeding end 111 and a short circuit 112. A signal so...

Abstract

The invention discloses a communication apparatus. The apparatus comprises a support plate and an antenna system. The support plate comprises a current-conducting plate and a non-current-conducting plate. The current-conducting plate possesses a first edge and a second edge. The antenna system is located on the first edge of the current-conducting plate. The antenna system at least comprises a first antenna and a second antenna. The first antenna and the second antenna are operated in at least one first frequency band. A distance of the first edge and the second edge of the current-conducting plate is close to 0.25 times of a wavelength of a minimum frequency of the first frequency band and the distance is less than a length of the first edge. The antennas of the invention can reach good isolation without an isolation element and antenna efficiency basically maintains the same.

Description

Technical field [0001] The present invention relates to a communication device, in particular to a communication device including a multi-input multi-output (MIMO) antenna system with high isolation. Background technique [0002] With the increasing demand of the public for data transmission, the support of relevant communication standards for transmission rates has also been continuously improved. For example, IEEE 802.11n can support the operation of MIMO technology, thereby increasing the transmission rate. Related mobile communication technology standards, such as long term evolution (LTE, long term evolution) systems, also support MIMO operations. It can be seen that the operation of multiple antennas has become a future trend. Since multiple antennas must be arranged in a limited space in a mobile communication device, the isolation between the antennas becomes a problem that must be considered. [0003] Traditionally, the method to improve the isolation of the MIMO antenn...
