Next–Generation Antennas. Advances and Challenges

Antenna design and wireless communication has recently witnessed their fastest growth period ever in history, and these trends are likely to continue for the foreseeable future. Due to recent advances in industrial applications as well as antenna, wireless communication, and 5G technology, we are witnessing a variety of developing and expanding new technologies. Compact and low-cost antennas are increasing the demand for ultra-wide bandwidth in next-generation (5G) wireless communication systems and the Internet of Things (IoT). Enabling the next generation of high-frequency communication, various methods have been introduced to achieve reliable high data rate communication links and enhance the directivity of planar antennas. 5G technology can be used in many applications, such as in smart city applications and in smartphones. This technology can satisfy the fast rise in user and traffic capacity in mobile broadband communications.

Sayyor syujetli dostonlar-adabiy manba

Jahon so'z san'ati tarixida shunday noyob adabiy-poetik hodisalar mavjudki, ular qadimiyligi, davomiyligi yashovchanligi, umrboqiyligi bilan ajralib turadi. Ana shunday fenomeniardan biri epik va liro-epik asarlardagi sayyor syujetlardir. Ma'lumki, syujet epik turdagi janrlarga xos badiiy yaratmalardagi eng asosiy alomat sanaladi. Qahramon (lar ) hayoti, faoliyati, uning xarakterini syujetsiz, ya'ni badiiy matndagi voqea tizimisiz tasavvur qilish mumkin emas.
