Design and Frequency Characterization of a Rose Antenna Produced with 3D Printing

Antennas are devices used to receive or transmit electromagnetic waves. Antennas can be designed in different shapes for various purposes. Additionally, the radiation patterns of antennas can vary. The radiation pattern indicates how strong the antenna is in a particular direction. Changes in parameters such as the overall operating frequency and input reflection can be observed depending on the shapes and manufacturing materials of the antenna. In recent times, 3D printers have been used for practical antenna production. In this study, the crown petals of a rose were drawn using the AutoCAD program. After obtaining a hard PLA print from a 3D printer, the petals were covered with aluminum tape to provide conductivity. The antenna design, transformed into a 3D rose pattern, was given its final natural antenna appearance by soldering an SMA connector. The antenna’s usability within specific frequency bands was discussed through measurements of the S11 parameter using the Nano VNA V2 plus 4 measurement device.
