Abstract :
A novel internal antenna for hand-held mobile communications is presented. Topics covered include antenna bandwidth, description of the radiation-coupled dual-L antenna, the CAD system for wire-grid modeling, bandwidth, impedance, the shielding case, and the radiation pattern. This radiation-coupled dual-L antenna radiates isotropically, and offers a number of design options for impedance matching. Compared with an inverted-F antenna of equal height, its bandwidth is higher by at least 50%. Numerically calculated results based on a wire-grid model of this antenna agree well with measurement of bandwidth, input impedance, and radiation patterns. A major advantage of this antenna is its enhanced bandwidth without external matching networks in a small occupied volume
