摘要：
A surface-mount loop antenna very suitable for application in the mobile devices such as the PDA (Personal Digital Assistant) phone for quad-band operation is presented. The antenna comprises of a loop metal pattern for generating two wideband resonant modes at about 900 and 1800 MH: to cover the AMPS/GSM/DCS/PCS bands and a central coupling stub as the feed structure. Although quad-band operation is obtained, the antenna occupies a small volume of 7 x 8 x 60 171,113 or about 3.4 cm(3) only and is easy to be embedded inside the PDA phone as nn internal antenna. Details of the proposed surface-mount loop antenna are presented and discussed. (C) 2007 Wiley Periodicals, Inc.
