Description

Cover for 5G mobile communication portable terminal {COVER FOR 5 GENERATION MOBILE TELECOMMUNICATION DEVICE}

The present invention relates to a cover for a 5G mobile communication portable terminal, and more particularly, to a cover for a 5G mobile communication portable terminal connected to a mobile communication terminal to support 5G mobile communication.

Ahead of the commercialization of the 5th generation (5G) mobile communication standard, rapid changes in antenna technology are expected. This is because overall changes such as the material and shape of the antenna are inevitable in that it transmits and receives signals in the ultra-high frequency band compared to the existing 4G technology.

The reason why the introduction of 5G technology is expected to fundamentally change the antenna industry is because of frequency. The 5G standard 'New Radio (NR)', which is being commercialized by 3GPP, a global mobile communication standardization cooperation organization, exchanges data in the high-frequency band of 24 GHz to 100 GHz and below 6 GHz.

However, if the millimeter wave (mmWAVE) frequency band of 24 GHz or higher is used, the signal approaches the properties of light and cannot avoid obstacles such as mountains or buildings. The wavelength is also only 1 to 10 mm, so the area where each base station can transmit and receive frequencies is also narrow.

In addition, if a signal with a high frequency band is not sent in one direction, a lot of energy is consumed in transmitting and receiving the signal.

For this reason, beamforming and Massive MIMO technologies are used in 5G mobile communication.

As a result, in order to implement beamphobing and MIMO technologies, a larger number of antennas must be mounted on mobile communication portable terminals.

However, there is not enough space to install a large number of 5G antennas in a very dense space because many parts and antennas are already deployed in the current mobile terminal.

In order to reduce frequency interference, a certain distance must be maintained between antennas.

In order to overcome all these difficulties, it is necessary to make a smooth transition to the 5G mobile communication system by utilizing portable terminal peripherals.
