Abstract: Recent advances of our researches on planar leaky-wave antennas are summarized. The planar leaky-wave antennas are fabricated on microstrip line and substrate integrated waveguide (SIW), which are low profile, low cost and easy to manufacture. They can inherently generate a narrow beam that scans with frequency. Researches were performed with special emphasis on the theoretical calculation and the excitation of the first higher mode in the microstrip leaky-wave antennas, and the endfire radiation and the circular polarization with the SIWleaky-wave antennas.
