Proximity-Coupled-Fed Logo Antenna Design Operating in the C Band

Logo antennas are extensively utilized in various fields and in this era where aesthetics, advertising and recognition are important as well as functionality, the demand for such antennas is also on the rise. In this study, a logo antenna with the emblem of Aydın Adnan Menderes University operating in the C band (4.87 GHz) was designed and examined for use in wireless communication. In the antenna design, two FR4 layers with a thickness of 1.6 mm and an epsilon value of 3.8 were utilized, and the proximity-coupled feeding method, which is one of the non-conducting feeding types, was preferred for the antenna. The antenna was designed using the CST Microwave Studio program ,and in the simulations, bandwidth, S11, gain and radiation pattern were analyzed. The antenna dimensions showing the best performance were determined by performing parametric sweeps. As a result of simulation studies, the bandwidths of the designed antenna for |S11|<-10dB and |S11|<-6 dB return loss values were found to be 241 MHz and 483 MHz, respectively. The maximum gain of the antenna was found to be 4,567 dBi and the VSWR value was found to be 1.45.
