This paper presents the family of logarithmically periodic toothed planer antennas. In this the dimensions of the succes-sive sections were increased in geometric progression for a wide bandwidth usage. A band width of 7% for trapezoid toothed, 26% for zigzag toothed and 50% for cross-toothed VSWR < 2 has been obtained from the proposed antennas. Investigations on the gain and radiation characteristics have been carried out. The investigations show that the pro-posed designs not only offers the enhanced bandwidth but also possesses the same characteristics over the desired fre-quency band at same probe feed position.
