A Hybrid Antenna Structure for Cognitive Radio Applications

Due to rapid growth of 5G communication and mobile systems, there is a huge requirement of wideband, multiband and UWB antenna. Considerable research is going on to create new appropriate solutions to satisfy the challenging constraints of 5G wireless communication systems. In this paper we optimize the antenna size to reach essential requirements for spectrum sensing and communication. In this article a reconfigurable antenna and a UWB antenna is built on the single side of the substrate. Even though both UWB monopole and narrow band antennas are integrated together but they are excited by different ports and work independently. So, the final combined antenna detects and communicate over a wide frequency range from 3GHz to 13GHz.
