Antena Multibanda Semi-Espiral CPW para Aplicações no 5G sub-6 GHz

Modern wireless communication systems increasingly need radio frequency devices capable of meeting their operating specifications. In this work, an antenna with multiband characteristics based on semi-spiral geometry and coplanar waveguide feed line is proposed for applications in the 5G sub-6 GHz standards. A study is done on the physical parametersof the spiral patch and feed line geometry. The prototype built was subjected to measurement where four operating bands were obtained, which were centered at 1.36, 1.71, 2.47 and 3.65 GHz, therefore, possibly applicable in the specified standards
