Compact antenna

This paper proposes a dual-band PIFA antenna operated at 28/38 GHz for 5G communication systems. The PIFA antenna consists of two dielectric layers and an air gap is inserted between these two layers. Both substrates, namely Roger RT dielectric, have a relative dielectric constant of 2.2 and a thickness of 0.127 mm.
