Multiband Chip Antennas for Mobile Handsets

In this thesis, the study mainly focuses on developing multiband chip antennas for mobile handsets. Three possible solutions and their extended and integrated designs are presented. By using the dielectric material as the chip base, the chip antenna can be smaller in size and simpler in design. Most of the applications of the traditional chip antennas are rarely used as the mobile phone antenna and are commonly designed with a single operating band to cover GPS or WLAN operation only. Different types of the antennas are proposed in the thesis. The metal patterns of the monopole and loop antennas are manufactured inside the chip base with an occupied volume of generally less than 0.8 cc, some even as small as 0.3 cc. Electronic components like the lens of the embedded camera and the speaker can be integrated close to the chip antenna with little influences on the radiation characteristics. Consequently, the developed chip antennas are suitable for mobile communications and can cover not only GSM850/900/1800/1900/ UMTS bands but also WLAN/WiMAX bands.
