Abstract :
A dual and wide band internal antenna with a low profile, compact size and light-weight is required for a personal computer (PC) in high-speed wireless LAN systems, such as IEEE 802.11a using the 5 GHz band (5.15-5.875 GHz), and IEEE 802.11b/g using the 2.4 GHz band (2.4-2.5 GHz). Many types of antennas have been proposed and investigated. The paper proposes a compact dual and wide band internal planar antenna for a PC in wireless LAN systems. The results calculated using an electromagnetic simulator are described to demonstrate the usefulness of the proposed antenna. Good impedance and radiation pattern characteristics are obtained.
