Previous wideband or ultrawideband antennas have been bulky such as horn, helical and log periodic antennas. Conventional microstrip antennas are planar, conformal and inexpensive but have narrow frequency bandwidths. It is extremely desirable to have antennas with all the advantages of microstrip antennas and large bandwidths. The proposed wideband planar leaky-wave microstrip antenna provides such a need.
