Abstract

High-power wide band helical antenna is designed, analyzed and manufactured in the Electrical and Electronics Engineering Department Laboratory of the Faculty of Engineering of Karabuk University. Krausss formulas are used in the design of the proposed antenna and Ansys HFSS program is used to simulate it. After the antenna is designed, its dimensions are optimized and analyzed. Thus, the desired antenna parameters were obtained. To maximize performance and match the input impedance to that of the antenna, the diameter of the winding wire has been increased, resulting in a lower VSWR and a much greater operational bandwidth. The proposed antenna has 4.5 turns, a wavelength of 51.72 mm, a height of 58.05 mm, spacing of 12.9 mm, and a diameter of 16.1 mm. This antenna resonates at the 5.8 GHz center frequency and has a bandwidth of 2.92 GHz. The bandwidth is 50.34% of the center frequency value. The presented antenna on Teflon substrate has achieved a gain of 12.06 dB. The proposed antenna also can be used for various wireless applications such as wideband, 5G and drone applications.
