Abstract

A compact CPW-fed monopole antenna over a periodic arrangement of artificial magnetic conductor (AMC) has been developed for Ka-band application. The 50 Ω coplanar waveguide fed is used to achieve a large bandwidth ranging from 25.76 to 35.86 GHz. The proposed monopole is designed on Roger RT/Duroid 5880 substrate with dielectric permittivity εr = 2.2 and tanδ = 0.0001. The full wave simulation tool Ansys HFSS 19.1 is used to simulate and design the proposed antenna. The radiation characteristics of monopole antenna are improved by using AMC reflector surface. The square AMC with four stubs and circular slot is designed for 28 GHz. By using AMC reflector, it is demonstrated that the gain and bandwidth are increased upto 8.76 dBi and 25.76–35.86 GHz (32.7%).
