Problems solved by technology

If it needs to be designed for multiple input and output (Multi input and Multiple Output, MIMO), the structure is complex and the volume is large. In addition, this type of antenna needs to add a matching circuit at the feeding point to achieve a good match, so the production cost is relatively high.

Embodiment Construction

[0015] see Figure 1A , shows a schematic structural view of the printed antenna 10 disposed on the first surface 42 of the substrate 40 in the embodiment of the present invention. The substrate 40 has a first accommodating area 50 and a second accommodating area 52 (such as Figure 1B shown), are respectively arranged on the first surface 42 and the second surface 44 of the substrate 40 (such as Figure 1B As shown), the first accommodating area 50 and the second accommodating area 52 are used for setting electronic components. In this embodiment, the printed antenna 10 is a multiple-input-output antenna.

[0016] The printed antenna 10 includes a first antenna 20 and a second antenna 30 symmetrically disposed on the substrate 40 adjacent to two side edges. The first antenna 20 includes a signal feeding part 22, a pair of grounding parts 24, a first body 26 and a second body 28 (such as Figure 1B shown). In this embodiment, the signal feeding part 22 is a 50-ohm transmis...

Abstract

The invention relates to a printed type antenna, which is arranged on a base plate provided with a first surface and a second surface. The invention comprises a first antenna, and the first antenna comprises a signal feed-in part, a pair of grounding parts, a first main body and a second main body. The grounding parts are arranged at the both sides of the signal feed-in part. The first main body is arranged on the first surface of the base plate, and comprises a first radiation part used for enhancing gain and a second radiation part used for increasing radiation efficiency. The signal feed-in part is communicated with the second radiation part. The second main body is arranged on the second surface of the base plate, and comprises a third radiation part and a fourth radiation part, and the third radiation part and the fourth radiation part are symmetrically distributed at the both sides of the signal feed-in part. The third radiation part and the fourth radiation part are respectively communicated with the parts. The multi-input and multi-output characteristics can be realized through the printed type antenna, and the occupied area can be effectively reduced.

Description

technical field [0001] The present invention relates to an antenna, in particular to an antenna applied to a wireless communication device. Background technique [0002] With the rapid development of the communication industry, there are more and more types of wireless products, such as the widely concerned WLAN (Wireless Local Area Network) products, and its application range is more and more extensive. For the access point (Access Point) of the wireless local area network and the wireless network card of the MINI-PCI, PCMCIA or USB interface of the notebook computer, or the wireless communication equipment such as the mobile phone applied to the personal communication, in order to be convenient to carry, generally need Designed to be small in size. The antenna is an essential element of the above-mentioned wireless communication device, so reducing the size of the antenna is a solution to reduce the size of the wireless communication device. The prior art often adopts a ...
