Embodiment Construction

[0016] See Figure 1-3 A preferred embodiment of the present invention provides a wireless communication device 200, which may be a mobile phone, a tablet computer, a personal digital product, and the like. The wireless communication device 200 includes a slot antenna 100, a circuit board 220, and a metal frame 240 spaced apart from the circuit board 220. The wireless communication device 200 of this embodiment is described by taking a mobile phone as an example. Therefore, the wireless communication device 200 of this embodiment also has the basic components of a mobile phone, such as a headset interface 260. However, these basic components are widely known by those in the industry. It is well-known and not the focus of improvement in this case, so I won't repeat it here.

[0017] The slot antenna 100 includes at least one feeding point 222, a plurality of grounding points 224 and a radiation part 226. The feed point 222 and the ground point 224 are both connected between the ...

Abstract

The invention discloses a wireless communication device comprising a slot antenna, a circuit board, and a metal frame. An interval is arranged between the circuit board and the metal frame. The slot antenna comprises a feed-in point, a grounding point, and a radiation part. The feed-in point and the grounding point are connected between the circuit board and the metal frame. The radiation part is a part of the metal frame, and the radiation part and the circuit board are used to form a slotted hole. The circuit board is provided with a multiplexing band-pass filter, a plurality of matching circuits, and a plurality of radio frequency chips. The slot antenna, the multiplexing band-pass filter, the matching circuits, and the radio frequency chips are sequentially connected. The slot antenna can work in different communication frequency bands, and therefore the size of the wireless communication device can be reduced.

Description

Technical field [0001] The present invention relates to a wireless communication device, in particular to a wireless communication device with a slot antenna. Background technique [0002] In wireless communication devices, antenna devices used to transmit and receive radio waves to transmit and exchange radio data signals are undoubtedly one of the most important components in wireless communication devices. In recent years, the continuous emergence of various communication systems and applications that use different operating frequency bands has led to the development of antenna designs that cover multiple system frequency bands. In order to ensure that the wireless communication device can transmit signals in a variety of wireless communication systems using different operating frequency bands, the antenna device must be able to transmit and receive signals of multiple different frequencies. On the other hand, slot antennas are generally complex in structure, but because the ...
