“…Microstrip patch antennas have many uses in wireless communication systems, amateur radio and satellite applications, GPS, and mobile applications owing to their advantages such as light weight, compact size, low power consumption, and shape-changing capability without sacrificing signal quality. Conversely, scholars have made significant contributions to antenna design in order to address the difficulties associated with wireless communication systems, specifically with regard to data handling capacity in both wideband and multiband operations [5,6,7,10,13,14,21]. The Bow-Tie antenna is one of the many varieties of micro strip patch antennas, and it is considered a good option for a number of wireless applications, including amateur radio applications.…”

This article presents the construction and examination of a Bow-Tie antenna array on a FR4 substrate. The proposed antenna geometry was chosen as a hybrid structure known as a semi-circled horn-like bow-tie antenna, and an array of four antennas in a single row was built. The semicircle diameter and the feedline length of a single antenna are 41.66mm and 21.44mm respectively. CST Microwave Studio was used for design and simulation. The proposed antenna array was printed on a 1.6mm thick substrate with a length of 325.00mm, a width of 56.00mm and a dielectric constant (ℇr) of 4.4. According to the experimental results, the proposed antenna has a return loss of-20.12dB at S11, a VSWR of 1.2 at S11 and Maximum Gain of about 2.94dB. The antenna array was tested in the 2.4GHz to 2.5GHz frequency range. The proposed semi-circled bow-tie antenna array was compared to the rectangular bow-tie antenna array, and it was observed that the proposed antenna array has outperformed the rectangular bow-tie antenna array at 2.45GHz. As a result, the proposed antenna array is a suitable candidate for Mobile and Amateur Radio Applications.
