Design and development of U-notched corner truncated square microstrip antenna for X to Ku band operation

Abstract

This article reports the design and development of horizontally U-notched corner truncated square microstrip antenna (UCSQMA) for dual-band operation. If one more U-notch is placed perpendicular to the horizontal U-notches on the radiating patch, the antenna resonates for triple band of frequencies. Further, if H-slot is placed on the ground plane of this antenna, the antenna operates for single band and gives a maximum impedance bandwidth of 82.68% covering X to Ku bands without changing the nature of broadside radiation characteristics. The proposed antenna may find applications for the systems operating in the frequency range of 7.53 GHz to 18 GHz. Details of antenna design are described and experimental results are discussed. © 2012 Wiley Periodicals, Inc.
