Talk about the development of 4G antenna technology

The progress of wireless antenna technology has led to the rapid development of 4G era, and the antenna has become a bottleneck of the current handheld terminal. At present, whether in the domestic mobile phone antenna market share is relatively large old antenna manufacturers to the transformation of some representatives of mobile terminals, are facing the great challenges brought by 4G antennas. Let's explore what causes this technical difficulty.

4G antenna technology is what we usually refer to as the fourth generation of mobile phone mobile communication standards, referring to the fourth generation of mobile communication technology, foreign language abbreviation: 4G antenna technology.

Global mobile data users expect their devices to be connected at high speeds anywhere in the world. This expectation places a huge burden on network and device performance. In mobile data equipment, antenna is the most important part of the "contact" network, optimizing antenna performance becomes more and more important. However, the challenges of designing 4G antennas in smartphones and tablets are formidable.

In China, we often say five modes and ten frequencies. This means that different carriers use different standards and use different wireless bands. In addition to Bluetooth, WIFI, radio, GPS and so on. No contact with the outside world is possible without an antenna. And now mobile phones and tablets are developing in the direction of thin and light, which leaves less and less space for the antenna.

Today we look at how antennas fulfill this task and challenge in the 4G era. 4G antenna technology is a combination of 3G and WLAN, and can quickly transmit data, high quality, audio, video and images. 4G antenna technology can download at speeds of more than 100Mbps, 25 times faster than the current home broadband ADSL(4 megabits), and can meet almost all users' requirements for wireless service.

We know that there are many factors that affect the antenna performance of handheld mobile communication devices. While these factors are related, they generally fall into three broad categories: antenna size, cross-coupling between multiple antennas, and device usage models.
