A Rectangular Ring Slot Microstrip Patch Antenna for Multiband Applications

Abstract

A Rectangular Microstrip patch antenna (MPA) for multiband applications is designed using slotting technique. The proposed antenna supports different range of frequencies, the antenna can be operated at four different bands i.e., X, S, Ku, and C band. The antenna is designed using FR-4 epoxy substrate with dielectric constant of 4.4 and loss tangent of 0.02 The dimensions of the substrate are 36.27 X 30.03 X 1.5748 mm 3 designed antenna resonates at the following frequencies 3
