Abstract: communications due to their compactness, lightweight, low profile and conformability to any structure. The size of the conventional microstrip antennas such as rectangular, circular, and triangular, patches is large and unsuitable to be used in many applications, especially at the lower microwave range. Various techniques have been investigated in the literature to reduce the size of conventional structures. One can cut slits or slots on the basic shapes which will result in new compact geometries like slotted L-shaped and ring microstrip antennas. The main disadvantage of the resulting compact structures is the associated bandwidth reduction. However, bandwidth can be increased by adding lossy elements in turn of lower antenna efficiencies. One possible solution to avoid the use of lossy elements is the use of tunable or reconfigurable antenna concept [1]. In this case the small size antenna would not cover all bands simultaneously. Instead, it will provide narrower instantaneous bandwidths in a wide tuning range with better antenna efficiencies. © 2010 IEEE.
