Abstract
The high isolated dual‐band inverted‐F diversity systems for portable devices, operating in 2.4 GHz band (2400–2484 MHz) and 5.2 GHz band (5150–5350 MHz), are presented. To reduce the mutual coupling and get high isolation between two internal dual‐band antennas, we proposed the small N‐section resonators in the form of slots on the ground plane. The optimized small size resonators for high isolation, antenna radiation efficiency, and high effective diversity are analyzed. Because of their small size, N‐section resonators can be widely used in small diversity systems that require high isolation between antennas. © 2007 Wiley Periodicals, Inc.
