N2 - Varies multi-band antenna concepts In the 1990s, the mobile phone industry experienced a dramatic development. The first stage was from analog standard to digital standard development, for example, analog standard such as AMPS (Advanced Mobile Phone System), NMT (Nordic Mobile Telephone) and ETACS; digital standard such as GSM, D-AMPS and CDMA. The second stage was from single band to multi-band due to the strong capacity requirements. DCS1800 and PCS1900 were introduced in the middle of 1990s. Ying first proposed a dual band non-uniform helical antenna [1, 2], which became later a popular antenna for dual band mobile phones. In the same time, P. Haapala proposed a dual band mono-helix antenna [3]. G. Hayes proposed a meander type dual band antenna [4]. In 1997, Ying proposed a branch multi-band antenna [5] [6], which has been applied into several Ericsson mobile phones. Andersson proposed a broad band shark fin antenna later [7]. In 1998, an internal antenna was introduced to the mobile phone, which caused a lot of market interest. We started some research work in this area and soon Ying proposed an internal printed spiral antenna and a dual band printed antenna [8] [9]. Later in the same year, a dual band internal antenna for a mobile phone was developed [10]. The antenna concept is based on a branched PIFA antenna. More development work was performed, in order to enhance the bandwidth to fulfil multiband applications. A parasitic element coupling antenna was developed [11], the practical antenna can meet the application of GSM/DCS/PCS tri-band [12, 14]. At the same time, more frequency bands were introduced, UMTS, Wireless LAN are the examples. Ying proposed a tuneable antenna for this kind application [13]. To meet the global system requirement, some so-called penta band antenna concepts are proposed recently [15, 16, 17]. The capacitive feeding and high dielectric loading are introduced in the new concept. The multi-band technique is still a hot topic in the mobile terminal application.
