Ceramic chip antenna for WWAN operation

A WWAN ceramic chip antenna suitable for mobile phone applications has been proposed and studied. The proposed ceramic chip antenna, although occupying a small volume of 2.5 x 5 x 40 mm 3 (0.5 cm 3 ) only, can provide two wide operating bands at about 900 and 2000 MHz for covering GSM850/900 and GSM...

Description
Summary:A WWAN ceramic chip antenna suitable for mobile phone applications has been proposed and studied. The proposed ceramic chip antenna, although occupying a small volume of 2.5 x 5 x 40 mm 3 (0.5 cm 3 ) only, can provide two wide operating bands at about 900 and 2000 MHz for covering GSM850/900 and GSM 1800/1900/ UMTS operation, respectively. By using a high-permittivity ceramic chip base in this study, the occupied volume of the antenna can be greatly reduced. In this case, the use of a simple asymmetric T-shape metal pattern embedded inside the ceramic chip base can result in wide operating bands obtained for WWAN operation for the proposed antenna. For frequencies over the operating bands, good radiation characteristics have also been observed.
