Design and Analysis of a Compact Rectangular Microstrip Antenna with Slots using Defective Ground Structure

Abstract In this paper a rectangular microstrip antenna with slots as shown on Fig. 2. is proposed. In the absence of slots and defective ground structure (DGS) the structure found to resonant at 5.22 GHz. When the DGS and slots are introduced a frequency shift of 5.22 GHz to 1.56 GHz is observed. The main contribution of this paper is the miniaturization of 91% which is very much encouraging.
