Abstract

A reconfigurable low-profile branched monopole antenna has been developed. It can operate at six different frequency bands that are 800 MHz, 900 MHz, 1.7 GHz, 1.9 GHz, 2.4 GHz, and 5.2 GHz. The developed antenna is compact and has a low-profile structure with dimensions of 96 mm times 9 mm times 3 mm, which makes it optimum for the laptop implementation. The antenna comprises two branches that are reconfigurable and is printed on a 0.05 -mm-thick Kapton substrate. Each branch is a multiband structure. Embedded switches are used for reconfiguration and are strategically positioned next to the ground plane to simplify the implementation of direct current (dc) biasing.
