According to the antenna theory, a linear antenna and an electric dipole are the two different concepts. An electric dipole is the primary radiation element with simple characteristics, and a linear antenna is an antenna commonly used in telecommunication systems of which properties depends on the size.

Wireless communications is one of the most active areas of research over the past and the current decades. In fact, the demand for wireless services has been changing from the regular voice telephony services to mixed voice, data, and multimedia services over the wireless media. Since the mid-1990s, the wireless industry has been advancing at an incredible speed. For example, the 2G cellular systems (such as GSM, D-AMPS, and IS-95) have significantly improved the spectral efficiency and network capacity to support wireless telephony services....

This book is the result of close cooperation between industry and academia, notably Ericsson and two universities in Sweden: Chalmers University of Technology (CTH) in Göteborg and The Royal Institute of Technology (KTH) in Stockholm. In 1987, a student at CTH presented her PhD thesis on the topic of conformal antennas. It was then considered an interesting but difficult technology with no immediate application.

ARRAY BACKGROUND Discovery of the first works on array antennas is a task best left to historians, but the two decades before 1940 contained much activity on array theory and experimentation. Some of the researchers were G. H. Brown, E. Bruce, P. S. Carter, C. W. Hansell, A. W. Ladner, N, E. Lindenblad, A. A. Pistolkors, S. A. Schelkunoff, G. C. Southworth, E. J. Sterba, and T. Walmsley. Primary journals were Proc. IRE, Proc. IEE, BSTJ, RCA Review, and Marconi Review. During World War II, much array work was performed in the United States and Britain....
