A 3D Printed Cubic Antenna Array for 2.4 GHz Wireless Communications

This paper presents a 3D printed cubic antenna arrar for 2.4 GHz wireless communication applications. The 3D printing technology has been employed to achieve a conformal design of the antenna elements with a cubic box, which makes it easy to be integrated with the compact and aesthetical WiFi products. The complete structure achieves a high radiation efficiency (more than 90%) and a dipole-like radiation pattern with the maximal gain of 2.08 dBi, while there is a good agreement on the simulated and measured results.
