A COMPACT SIZE HIGH FREQUENCY RECONFIGURABLE MONOPOLE ANTENNA FOR MULTIBAND APPLICATIONS

This paper describes a small and simple patch antenna that can operate in multiple nodes. Initially, the fifth generation (5G) of portable networks seeks to provide more efficient and precise interaction while also increasing internet bandwidth in the sub-6 GHz frequency range. As wireless communication technology advances, the demand for numerous wireless broadband in a particular system takes improved quickly, and traditional transmitters are no longer able to satisfy this new rule of cellular systems. The most popular approach for meeting this criterion is to create an ultra-wideband (UWB) antenna. Multi-band transmitters, on the contrary side, are an option. Wide-band or multi-band transmitters, on either hand, have a fixed operating frequency spectrum, which is a significant disadvantage. Even though using higher antenna sizes in conjunction with sophisticated structures adds a lot of complexity to the system, it limits its compact size and mass production. When creating an antenna, the effective length is an important quantity that is used to determine the radiation resistance and power. While existing research employs various types of stubs to extend the effective length of the antenna, there is still a restriction to attaining the high band frequency. Thus, to overcome all the above limitations in the existing methods, our proposed method designed a Compact Size High-Frequency Reconfigurable Monopole Antenna for Multiband- Multi-Mode Presentations. This research also proposes the active dimension of the monopole antenna is increased by using two circular stubs joined at the antenna’s edges. Overall, we outperform all other current strategies utilising our one-of-a-kind proposed strategy.
