ABSTRACT

In this research, a compact super-wideband monopole antenna is introduced. The antenna's electrical dimensions are 0.228λ × 0.144λ × 0.009λ, the λ represents the wavelength of the lowest operating frequency. The suggested antenna achieves a single operating band 10 dB between 2.8 and 40 GHz, a percentage bandwidth of 173.83%, and a BW ratio greater than 10:1. The suggested super wideband antenna has a large BDR of 5432.18 and a maximum gain of 6.6 dB. The antenna features a U-shaped radiating element and a rectangular, chamferedcornered partial ground plane to attain super wideband characteristics. The antenna has been designed to be compact and flat in structure while still providing adequate gain and a broad range of frequencies, which makes it suitable for a variety of uses in contemporary wireless communication. To increase the antenna, gain for ultrawideband applications, an FSS is developed. The FSS has a compact unit cell with physical dimensions of 18 x 18 mm2. When the FSS is used as a substrate, the antenna reaches a maximum realized gain of 10 dB. Additionally, at UWB frequencies, a gain amendment of up to 4.61 dB is observed.
