    Abstract

    The research presented here compares the weight and structural strength of several lightweight three-dimensional (3-D) metal printed fractal antennas to the equivalent metal-coated polymer 3-D printed antenna. Lattice structures are recognized for their advantages in providing lightweight, stiff, and shock-resistant structures. In this work, they are used to create a strong, lightweight metal antenna, which is even comparatively lighter than the metal-coated 3-D printed polymer antenna, and with higher structural strength. A radio frequency (RF) performance, similar to the Computer Simulation Technology (CST) simulation results, was confirmed for each antenna. Mechanical testing has also been conducted, to compare the strength-to-weight ratio of lightweight metal printed structures to that of the polymer one.
