This chapter will present and analyse a compact and dual frequency inverted L-F antennas for the operating frequency bands to meet the requirement for IEEE 802.11a/b/g, Bluetooth and ZigBee standards; the optimal design providing a compromise between size reduction and attainable bandwidth. The antenna consists of an F-shaped radiator and L-shaped parasitic element with the optimum (minimized) volume of 30 × 30 × 8 mm3, thus making it feasible to be adopted within the portable wireless electronic devices. By controlling the geometry parameters of the radiator, the lower resonant operating band can be tuned to achieve 8% bandwidth. Likewise, by optimising the geometry parameters of the parasitic element, the upper operating frequency band can reach the required 12.2% bandwidth. Both the computed and measured features of the present antenna are in good agreement.
