Abstract

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 MHz 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 × 8 × 60 mm^3^ or about 3.4 cm^3^ only and is easy to be embedded inside the PDA phone as an internal antenna. Details of the proposed surface‐mount loop antenna are presented and discussed. © 2007 Wiley Periodicals, Inc.
