In recent years, the demand for compact handheld communication devices has grown significantly. Antenna size is a major factor that limits device miniaturization. In the past few years, new designs based on the Smart antennas (SMA) have been used for handheld wireless devices because these antennas have low-profile geometry and can be embedded into the devices. Reducing antenna size generally degrades antenna performance.
