Design of Novel Coupled FED MIMO Antennas for Future Networks

The next-generation 5G smartphone is provided with a small broadband and dual band antenna for building the multiple input multiple output (MIMO) array. Antennas that are used before are capable of working in the particular frequency applications where quarter wave length radiators are subjected to miniaturization which offers to form limited bandwidth and low radiation efficiency. Less reception due to high return loss due to single patch antenna are used for each individual device. The most common radiator can be modified using the current techniques found in the open literature by bending, folding, meandering, and wrapping. Depending on the application, each method has a different set of benefits. When a finite antenna ground plane is introduced, it is frequently extended to include reconfigurable features. As a result, small, multiband antennas like these are frequently strong candidates for use in a variety of wireless applications. It is planned to work on a slotted multiband planar system for frequency bands such as IN GPS(1.575-1.665GHz), WLAN (2.4-2.545GHz), and WiMAX(3.27-3.97GHz). we proposed a design of a single antenna to cover more than 3 frequency band applications (multiband antenna) which can be used for existing wireless services. The miniaturization is done by having a two T shaped stub and a single U shaped stub to achieve the minimal return loss for the four spectrum. In spite of the extremely low ground clearances, the simulated results show good impedance matching, isolation, gain, directivity, and antenna efficiency performance.
