Performance Characterization of Radial Stub Microstrip Bow-Tie Antenna

Free registration required

Executive Summary

In hybrid and monolithic circuits, the radial stub will be used in common. When low impedance levels are needed, the behavior of conventional stub degrades as a result of the excitation of higher order modes. In this paper a novel radial stub feeding microstrip bow-tie antenna is designed to operate between C and X band and its performance characterization is presented. This antenna is having simple structure and topology over other stub loaded antennas. In addition the proposed antenna adjusts to the desired frequency easily. Antenna output parameters like radiation pattern, axial ratio, directive gain and quality factor are simulated and presented in this current work.
