Description

Antenna module and wireless network communication device having the same

The present invention relates to an antenna module, and more particularly to an omnidirectional dual-frequency antenna and a wireless network communication device having the antenna module.

In recent years, due to the booming development of the wireless communication industry, portable wireless communication devices such as mobile phones or personal digital assistants have become a necessity for people's lives, and have created a convenient living environment. However, in such portable wireless communication devices, the antenna device plays an important role in transmitting and receiving wireless signals. Therefore, the operational characteristics of the antenna device directly affect the wireless signal transceiving capability and quality of the wireless communication device.

In general, a well-designed antenna device is a very important part of the bandwidth in addition to the lower return loss. In order to enable the user of the wireless communication device to receive the wireless signal more conveniently and clearly, the wireless communication system does not use different signal transmission bands to communicate, and the current wireless communication device has increased the number or volume of the antenna device. In order to enable the wireless communication device to transmit and receive wireless signals in a large bandwidth or multiple frequency bands. However, in the trend of increasing component bulk density and increasing miniaturization of wireless communication devices, the conventional approach has been unable to meet the demand.

Antennas that are traditionally used in wireless networking products may use dipole or monopole antennas, and these types of antennas have a field coverage of approximately 360 degrees. From the application point of view, its advantage is that more users can enter the Internet through the bridge, but because the antenna gain is not high, the wireless communication distance is limited. In order to increase the gain, a directional antenna can be applied to increase the transmission distance; but the disadvantage is that users outside the directional antenna field cannot have good transmission efficiency; therefore, the omnidirectional antenna is covered with a larger signal. The wireless network communication users who are catering to different directions and distances will also be born.

In general, electronic products with wireless communication functions, such as wireless network bridges, wireless network routers, and wireless network sharers, transmit or receive radio waves through wireless antennas to transmit or exchange radio signals. To access the wireless network. Therefore, in order to enable the user to conveniently access the wireless communication network at any time, the present invention achieves omnidirectionality and greater signal coverage in a more ideal antenna setting mode to avoid the problem of receiving dead angles. Further strengthening the quality of network communication is the main development goal.

The main object of the present invention is to provide an antenna module that is configured to be omnidirectional 360 by three sets of horizontal radiators disposed on a horizontal substrate and three vertical radiators perpendicular to the vertical substrate of the horizontal substrate. The dual-frequency antenna module covering the range further improves the gain value and reduces the dead angle.

For the above purposes, the antenna module of the present invention comprises: at least one horizontal substrate, and at least three sets of vertical substrates. The horizontal substrate comprises: a top surface, a bottom surface, and at least three sets of horizontal radiators, and the horizontal radiation systems are disposed on the top surface at intervals. The vertical substrate systems respectively include: a vertical radiator, and the vertical substrates are respectively spaced around and vertically disposed on the bottom surface of the horizontal substrate, and are respectively located at a central interval of the two horizontal radiators; wherein The horizontal radiation systems are perpendicular to the vertical radiators.

The horizontal radiator and the vertical radiation system are respectively composed of a long antenna and a short antenna, and respectively oscillate to generate a first frequency and a second frequency to achieve the function of dual frequency. The first frequency is a low frequency band having a frequency range of 2.4 GHz; the second frequency is a high frequency band having a frequency range of 5 GHz. The wireless network communication device having the antenna module of the present invention obtains a better radiation field type and a higher gain value due to the horizontal radiator and the unique arrangement of the vertical radiator, and can greatly improve the performance of the antenna module to reach the signal. The purpose of omnidirectional antennas with high coverage.
