City University of Hong Kong, or CityU for short, was founded in 1984, formerly known as the City Polytechnic of Hong Kong, and was upgraded to City University of Hong Kong in 1994. Each year, CityU offers about 130 high-quality undergraduate and research degree courses of different levels and majors to about 20000 students. The university now has schools of business, humanities and Social Sciences, science and engineering, creative media, energy and environment, and law. Apart from the school of energy and environment, the above-mentioned colleges are now open to the mainland. More than 48% of the nearly 600 outstanding professors from 30 countries, including fields and Wolff prize winners, 10 world-class academicians, 12 Yangtze scholars, 17 members of the international society of electrical and Electronic Engineering (IEEE), 6 Fulbright Fulbright senior scholars, and 5 Croucher Most of them hold doctorates from well-known overseas universities, and have long held full-time teaching and research positions in overseas universities. For six consecutive years (2004-2009), CityU has been selected as one of the 200 best universities in the world in the times higher education supplement. From 2007 to 2009, CityU was also selected as one of the 150 best universities in the world. In 2009, CityU jumped to 124. CityU ranked 18 in the list of Asian universities. CityU ranked in the international higher education information institution quacquarelli symbols In 2010, the world university ranked 129, the Asian University ranked 15, the social sciences of CityU ranked 105, and the humanities, engineering and information technology ranked 107.
Technology | Some handheld electronic devices that require a pattern are equipped with directional printed antennas and a large ground plane. However, this configuration is not only cumbersome but also expensive for small devices. This disadvantage has inspired the invention of this new unidirectional antenna, which can receive and transmit wireless frequency waves. The antenna consists of a dipole antenna and a rectangular loop antenna, both of which are connected by a metal connecting element. Dipole antenna, loop antenna and metal connecting elements are all located on the substrate, which can generate unidirectional radiation pattern with 20dB front and rear radio waves. The working frequency range of the antenna is 2.4 GHz, and the peak magnification is 4.2 DBI at 2.44 GHz. |
Advantages | l Higher direct power transmission rate |
Possible applications | l A small device for demanding unidirectional radiation patterns |
