Wideband Planer Folded Dipole Antenna for Fast Wireless Communication

This work presents the design and simulation of a wideband planar folded dipole antenna (PFDA) aimed at enhancing high-speed wireless communication in the 5–6 GHz frequency band. The antenna is designed using ANSYS HFSS and fabricated on an FR4 substrate with a thickness of 0.6 mm. The proposed design achieves an impedance bandwidth of 420 MHz (5.38 – 5.8 GHz), a gain of 5 dB, and a narrow beamwidth of 20° × 30°, making it suitable for modern wireless, radar, and point-to-point communication systems. A return loss of –22 dB is observed at the center frequency of 5.5 GHz, indicating excellent impedance matching. The antenna demonstrates a stable radiation pattern, efficient power handling (up to 100 W), and linear polarization, contributing to reliable performance in high-frequency environments. By offering compactness and improved directivity compared to traditional broadband antennas, this design supports the development of portable, energy-efficient RF devices. Such advancements align with sustainable technology goals by enabling low-power, spacesaving, and cost-effective wireless systems for future communication infrastructure.
