Abstract: A defected ground structured circular monopole antenna is designed and presented in this research. The proposed antenna utilized closed loop resonator strips on both sides of the feed line. The overall dimension of the antenna is around 28×24×1.6 mm on FR-4 substrate with dielectric constant 4.4. The experimental results of the prototyped antenna on ZNB 20 vector network analyser are showing good agreement with simulated results on FEM based HFSS tool. A parametric analysis of the proposed antenna with respect to change in rate permittivity is also presented in this research.
