Abstract

Microstrip patch antennas are very popular due to their numerous advantages. This paper presents the design of a log periodic toothed planer trapezoid microstrip antenna. In this structure the dimensions of the successive sections were increased in geometric progression. A bandwidth of 18.18 percentage for voltage standing wave ratio less than two (VSWR<2) has been obtained from the proposed antenna. Investigations on the impedance and radiation characteristics have been carried out. The investigations show that the proposed antenna not only offers the enhanced impedance bandwidth, but also possesses the same characteristics over the desired frequency band
