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.

“…Considering this, an antenna with the characteristic of adaptability to various practical applications and standards is necessary. Hence, due to the dynamic characteristics and capability to modify properties such as polarization, radiation pattern, and frequency, along with system requirements, reconfigurable antennas have recently received a large amount of attention [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. In particular, a frequency reconfigurable antenna is beneficial for various applications.…”

A compact flexible multi-frequency antenna for smart portable and flexible devices is presented. The antenna consists of a coplanar waveguide-fed slotted circular patch connected to a rectangular secondary resonator (stub). A thin low-loss substrate is used for flexibility, and a rectangular stub in the feedline is deployed to attain wide operational bandwidth. A rectangular slot is etched in the middle of the circular patch, and a p-i-n diode is placed at its center. The frequency reconfigurability is achieved through switching the diode that distributes the current by changing the antenna’s electrical length. For the ON state, the antenna operates in the UWB region for −10 dB impedance bandwidth from 2.76 to 8.21 GHz. For the OFF state of the diode, the antenna operates at the ISM band (2.45/5.8 GHz), WLAN band (5.2 GHz), and lower X-band (8 GHz) with a minimum gain of 2.49 dBi and a maximum gain of 5.8 dBi at the 8 GHz band. Moreover, the antenna retains its performance in various bending conditions. The proposed antenna is suitable for modern miniaturized wireless electronic devices such as wearables, health monitoring sensors, mobile Internet devices, and laptops that operate at multiple frequency bands.
