Multilayer Perceptron Approach to PLA, PLA /Copper and PLA / Carbon Substrate Bow-tie Antenna Production

The study aims to observe the operating efficiency of Bowtie Antennas produced with three different materials under the desired conditions and to compare between materials. The produced antennas' desired feature is that the return loss (s11) in the low-frequency range is -10dB and below. This value is that the s11 value of the antenna is of great importance in detecting the tumor in the breast tissue. Parameters of antennas produced with different materials; The dielectric coefficient of the material used is the antenna diameter, the antenna substrate's thickness, and the length of the antenna legs. With these parameter values, s11 data at different frequency values in the frequency range of 0-3 GHz were obtained. Another purpose of the study is to observe the effect and accuracy of the parameters used on the result of the return loss estimation of the designed antennas. The data obtained were evaluated using the Multilayer Perceptron approach. © 2020 IEEE.
