Antenna research for PCS in Hong Kong

The topography in Hong Kong is very unfriendly to mobile communications due to tall buildings, narrow streets, the busy harbor, the mountainous terrain and the scattered islands. The local mobile phone industry is more a service provider than a product manufacturer. The majority of the frontline research on antennas for personal communication services (PCS) and other wireless communications services is conducted in local universities. Both the Wireless Communications Research Center of the City University of Hong Kong and the Center for Wireless Information Technology of the Hong Kong University of Science and Technology have strong research programs on antenna research for PCS and other wireless communications frequency bands. We present some of our previous work on antennas size reduction and bandwidth broadening.
