Problems solved by technology

Since the above-mentioned antennas are mainly used in mobile devices, such as laptops, when carrying laptops to other countries, since the digital TV bands between countries are not the same, the first antenna that can only be used in the UHF band is It is possible that the signal cannot be received in other countries; in addition, although the second antenna can be applied to UHF and VHF, it requires the user to adjust the length according to the needs, which is neither convenient nor necessarily able to achieve a good reception effect

Abstract

The invention relates to a wireless electric device, which comprises: the first and second antenna elements, and one switch, wherein said switch is connected to the first and second antennas; when the switch is on, the first and second antennas are connected, the wireless electric device processes the wireless signal in first frequency range; when the switch is off, the connection of first and second antennas are released, and the second wireless electric device processes the wireless signal in second frequency range.

Description

technical field [0001] The present invention relates to a wireless electronic device, an antenna module, and a method of operating the wireless electronic device. Background technique [0002] The popularization of digital TV is just around the corner, and digital TV terrestrial broadcasting (DVB-T) provides the possibility of receiving digital TV signals in mobile devices, such as vehicles, laptop computers, and palm-sized digital devices. In order to receive DVB-T signals, the mobile device needs two main components, one is a DVB-T tuner module and the other is an antenna. [0003] As shown in FIG. 1 , known TV applications use a monopole antenna (monopole antenna) 10 with adjustable length to receive digital TV signals. The bandwidth of VHF (Very High Frequency) ranges from 45MHz to 300MHz, while the bandwidth of UHF (Ultra High Frequency) ranges from 300MHz to 900MHz. Digital TV uses VHF and UHF frequency bands to transmit radio frequency signals, and in order to use d...
