History and Advancement of the Family of Log Periodic Toothed Planer Microstrip Antenna

Abstract

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.
