Generation Z" is a generation growing up in the environment of digital media and network. Under the influence of network, they gradually establish their own values and world outlook, and seek for self-identity in the vast world constructed by digital construction. Political economy of communication is a branch of communication, which is different from the empirical research path of other communication studies. It focuses on the influence of communication as an economic force on society and the control of communication activities by social political and economic authorities. From this perspective, every behavior of people hides its connotation of economics and a deeper level of criticism. It is from this perspective, this paper chose the Z generation this special group, contemporary college students as the research object, through the survey method to explore the basic characteristics of contemporary college students online media platform using behavior and objective law, trying to understand the psychological demands of related behavior behind its understanding of the behavior and for the recognition of the number of labor, Furthermore, the media literacy education of college students will be promoted faster and better, and the media literacy of college students will be comprehensively improved to help them use media in a better way.
In order to meet the needs of a variety of automotive communication services, vehicle antennas working in multiple frequency bands are emerging. It promotes the development of antenna in the direction of multifrequency and miniaturization. Based on the above research background, this paper designs a vehicle antenna for the requirements of mobile communication frequency band. The antenna consists of a half-t monopole and a half cone monopole, which are vertically placed on a metal floor. T-shaped branches mainly work at low frequency, while cone-shaped branches mainly work at high frequency. The tapered branch is used to improve the impedance matching, increase the bandwidth of the antenna, and the antenna miniaturization is realized by using half reduction technology. The antenna is processed and measured, and the working frequency bands are 720MHz-960MHz and 1.6GHz-4GHz, covering amps, GSM, LTE and 5G.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
