In this article, we have presented various techniques that are used for improving different parameters related to UWB antenna. In this Paper, we planned for MIMO antennas in contemporary wireless communication which enhances the bandwidth and gives compact antennas. The antenna band we notched is of planned MIMO which offers an bandwidth with the operational band-notched. The bandwidth capacity of the antenna is from 2.93-20 gigahertz with sharp rejection at WLAN-band with isolation of not exactly - 22 dB is accomplished for the whole band, by utilizing a simple modified shaped structure in the bottom plane, port isolation and transmission capacity are improved. The diversity execution performance is likewise contemplated and whole outcomes shows it’s a potential point of using MIMO based diversity antenna for ultra wide band applications which is demonstrate in this paper. The parameters to assess the performance of the MIMO are explained, the whole examination completed in different sections has been outlined

In this proposition, a traditional UWB antenna with twofold indent channels was intended for a few remote applications. The exhibited antenna is outlined having estimations of 30 × 35 × 1.6 mm3 with a fix of rectangular staircase design. The dismissal bands are WLAN at 5 GHz (5.1 - 5.8 GHz) and the satellite X-band from space to earth (7.25 - 7.75 GHz). The patch with a step design with a modified π-formed opening gets the ultra-wide band. The UWB scope of 3.1 - 10.6 GHz affirmed by FCC can possibly cause interferences in the various wireless systems applications.. With a specific end goal to lessen these interferences, we settled on the band indent. In this proposed outline, the WLAN has scores setting a U-molded opening in the patch and the X-band has indents with a reversed T-shape in the ground plane.

Green Communication

Generally one of the reasons for global warming is Co2 emission. The rapid growth of wireless communication is the reason for more emission. This creates more health issues, especially children. To reduce the issues, now the wireless communication is tilted towards green communication. Green communication cannot be achieved in single step. In this paper some of techniques are followed to achieve sustainable communication. The main objective of this paper is cognitive radio (CR), which makes use of spectrum in efficient way. In our proposed system, we focused on green cognitive cycle, Cognitive radio-Ultra wide band (CR-UWB) and Cognitive radio-Orthogonal Frequency Division Multiplexing (CR-OFDM). With these above methods we achieved better achievements in terms of efficiency, less time delay, resource utilization and low power for 5G wireless green communication.
