<span>A frequency reconfigurable microstrip transformed rectangular patch antenna consisting of two slots able to radiate in S-band and C-band is proposed. Spectrum occupancy is first analyzed using the data from literature and internet sources and hence spectrum holes are identified. A rectangular radiating patch is then designed for 5.8 GHz resonant frequency. A coaxial feed is used in the bottom by a suitable feed point. Two slots at an angle of +45 degree are made at the two corners. The electrical length of the patch is changed by using two varactor diodes in the slots. The varactors enable frequency reconfiguration in the band of frequencies that are unused or the spectral occupancy is very less. The return loss, voltage standing wave ratio (VSWR), and 2D-radiation patterns are analyzed for various values of the capacitances. high-frequency structure simulator (HFSS) is used for simulation. FR4 substrate which is economical, is used with height, h=1.6 mm, width W=25.33 mm, and length L=21.34 mm. On the substrate the rectangular patch is of width 15.73 mm and length 11.74 mm. The return loss and radiation patterns for different values of capacitances is presented. The tunability ratio obtained is 1.93. The results obtained agree with the standards.</span>

Wireless Body Area Network (WBAN) technology is gaining popularity in personal communication due to the expanding improvement in wireless technology. Wearable antennas are utilized in various WBAN applications including personal healthcare, entertainment, military, and many more due to their attractive characteristics and the potential for integrating lightweight, compact, low-cost, and adaptable wireless communications. A wearable reconfigurable antenna will allow a single antenna to operate at multiple resonant frequencies, radiation, polarization or hybrid between them, by using single or multiple active switching devices for signal transmission and reception in different parts of human body, rather than using multiple antennas. Over the years, several review papers were reported on wearable antennas which discussed the requirements and issues of wearable antennas in terms of their design, fabrication, and measurement. Nowadays, WBAN technology employs a single wearable reconfigurable antenna to perform multiple functions in different parts of human body. Recently, a significant amount of work has been carried out in the area of wearable reconfigurable antennas for WBAN applications. This paper presents a comprehensive review of the requirements and analysis needed for wearable reconfigurable antennas such as Specific Absorption Rate (SAR) for on-body analysis, investigation of the antennas in bending conditions, reconfigurable techniques and reconfigurable performance metrics.

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.
