Also included is a detailed description and analysis of their key patents. Each one’s strength and weaknesses are highlighted, and information is provided about their recent and future technology developments. This report provides a detailed comparison of the four main IP players: Samsung, Intel, Huawei, and Oppo Mobile. Comparison of patent portfolios held by main IP players Indeed, the main IP and market players (Apple, Samsung, Huawei, etc.) have commenced development of IP activity related to patch-antenna array.

Furthermore, our report details recent developments and trends that attest to the growing interest in patch antennas, which appear to be the preferred solution for addressing 5G’s technical challenges. This IP dynamic confirms the growing interest in low-profile, small-size, low-cost antenna, which are oft-used in handsets.

We have observed significant IP activity related to monopole and microstrip antenna. Pushed by the strong patenting activity of Chinese giants Oppo Mobile and Huawei, the IP segment related to handsets is strengthening and will continue growing in importance, thanks to the filing of a number of promising patents related to antenna for handset. The analysis shows that after a dominant period by US and European IP players involved in the development of antenna for infrastructures and networks, the IP activity related to antenna for handsets has started accelerating. In this report, Knowmade has manually segmented the patent corpus in terms of applications. Samsung and Intel appear to be the two leaders currently best-positioned to limit their main competitors’ patenting activity and freedom-to-operate.

Samsung, Intel, Ericsson, and Huawei – have begun extending their portfolios worldwide. Indeed, after an initial period of domestic patent applications, the main IP and market players – i.e. With more than 75% of patent applications still pending, much will change in the coming years. Today, the IP landscape related to antenna for 5G is still unsettled. In particular, we have noticed a large number of Chinese academic players, which is quite unusual in the telecom domain. This strong acceleration is pushed mostly by Chinese IP players, which account for more than 56% of IP activity. Since then, the number of 5G-related patent publications has seen a huge increase, with a growth rate of 113% from 2014 – 2018.

It was only in 2014 that the term “5G” began appearing in patents. Among all RF components now in development for 5G applications (filters, power amplifiers, RF front-end modules, etc.), the antenna has become a very complex, invaluable segment of the 5G network. 5G players must explore new frequency spectrums and more – especially the millimeter wave frequencies (from 20 GHz – 300 GHz). In addition to increase the data rate and bandwidth, 5G devices must be compatible with many data types. Along with mobile devices, 5G and 5G-related networks require the deployment of new infrastructures supporting specific protocols and operation modes, such as multi-input multi-output (MIMO), massive MIMO, beamforming, beam steering, carrier aggregation, and others. Indeed, 5G will affect global telecommunication services such as mobile phones, IoT (internet of things), vehicles, and more.
