Single-Layer Planar Monopole Antenna-Based Artificial Magnetic Conductor (AMC)

In this paper, a coplanar waveguide (CPW)-fed patch antenna is fabricated on layer of metasurface to increase gain. The fabrication Roger substrate with thickness 0.25 mm, the overall dimension proposed design being 45 × 30 mm3. size 24 14 mm3, and AMC unit cell 22 This designed based split-ring resonator cells forming an array artificial magnetic conductor (AMC). Meanwhile, operation 3.5 GHz enabled by etching slot ground plane small gap enhance gain improve impedance bandwidth when integrated metasurface. simulation planer monopole applied for 5G application. experimenter test performance in terms return loss, gain, radiation patterns. operating frequency range without MTM from 3.41 3.68 (270 MHz) 3.37 3.55 (180 MHz), respectively, improvements about 2.7 dB (without MTM) 6.0 (with at GHz. maximum improvement 42% AMC. has solved several issues overcome typical limitation conventional design. A circuit model also simplify estimation desired band. simulated CST microwave studio. Finally, measured. Result comparison between simulations measurements indicates good agreement them.
