Consequently, a wide bandwidth and a triple bandwidth are achieved. The bazooka balun balances the coaxial cable and increases the bandwidth. Additionally, the presence of a balun, or lack thereof, is examined. Here, a circular reflector is employed to achieve maximum gain, while a coax line feeds the dipole element. The proposed antenna is investigated using circular wire loop antenna designing and is, then, extended to a strip structure antenna. The simulated and measured results tie in closely with each other.This article thoroughly investigates a novel modified biquad dipole antenna with a simple structure, wideband, high‐gain and linear polarization key features for wireless communication systems fabricated on FR4 substrate. The broadside radiation pattern fills the entire band with maximum simulated and measured gains of 11.8 and 11.02 dBi, respectively. The simulation and experimentation results exhibit an impedance bandwidth of 105.4% (1.3-4.2 GHz) for ( S 11 < −10 dB). The simulated current distribution, experimented and simulated efficiency, radiation pattern, reflection coefficient and gain of the designed antenna are also examined. The resulting parameters demonstrate that the entire S, partial L and C IEEE radio bands comprise the bandwidth of the proposed antenna.
