    Abstract
    The times demand high requirements in technology, especially in the field of telecommunications. Now we have entered Beyond Fifth Generation (B5G) where all technology will be built in a network, such as smart buildings, smart devices and other IoT that use the Internet. The use of 5G technology has led to new needs or new concepts such as small antennas that can work at high frequencies. However, in its application there are still areas that have not been covered by 5G technology. Therefore, 5G technology is needed that can reach areas that use a lot of data that has a simple, small and compact design. In this paper, a method of increasing the gain of a microstrip antenna using a metasurface is presented. The proposed antenna is an antenna with a metasurface layer that has a 3 × 3 unit cell. The design of the metasurface is very simple using a single split ring (SSR). The proposed antenna is designed to operate at a frequency of 3.5GHz. This antenna design presents a parametric study of several metasurface structures and designs. This paper also describes the effect of current distribution on antenna performance, where the current flows in the vertical SSR patch element so that the magnetic induction has a direction that produces a magnetic field opposite to the magnetic field flux. If lring is constant and the distance between elements and the size of the unit cell are adjusted, we will be able to control the capacitance value. And if lring is constant while the distance between elements and the width of the slot are adjusted then wring will be the main parameter to control inductance. The addition of slots to the SSR will provide flexibility in adjusting the properties of the resonator. The antenna has been designed and successfully increased the gain of the microstrip antenna. The paper also describes the effect of current distribution on antenna performance. The antenna has a bandwidth of 220.4MHz and also has a radiation pattern of 61.9° for azimuth and an elevation radiation pattern of 81.3°. The method and design of the proposed antenna has the potential to provide data usage for small areas.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
