Smart Microstrip Antenna Designed for 4G Terminals

As the communication technologies are rapidly developing, the need of faster speeds is also increasing. The 4G in the future of the communication system and due to its advantages of entirely packet-switched networks, higher bandwidths to provide multimedia services at lower cost (up to 100 Mbps for mobile users), all-IP (Internet Protocol) based heterogeneous networks, Multiple systems at the same time (e.g., GPS and WLANs and CDMA), scalability of mobile networks (>10 times the capacity of 3G), the 4G is preferred. This paper is based on designing the antenna 4G terminals. The terminals include Mobile handsets, BTS and Access points. The main focus is on the handsets. The antenna should be smart enough to work in the 4G environment. Antenna size should be small to be implemented in a mobile handset and should be used as a transceiver. The antenna should cover bands allotted for 4G (i.e., 2.3–2.4 Ghz, 2.7–2.9 Ghz, 3.4–4.2 GHz, 4.4–4.9 Ghz) and suitable for mobile handsets. Once the above objective was achieved, we had to design our own antenna models which will be either wideband 4G antenna or covering one of the higher bands of 4G. This antenna could be used in the access points or in the handsets as they will not be of a big size.
