Analysis and Design of 3-D Printed Fractal Triangular Antenna for Wireless Communications Applications

With the progress of wireless communication systems, low profile, low weight and appropriate cost antennas are highly required for industrial revolution applications. Multi-band and wideband antennas are desirable in wireless communication systems, small satellite terminals, and other wireless applications. The 3–D printed antenna based on the Sierpinski fractal concept (Cantor slot patch) is studied, and the performance is discussed. All the antenna models are designed to operate for Bluetooth, WLAN, Wi–Fi system and S–band radar with return loss less than −10 dB, with operating bands around 2.45 GHz. In this paper, analysis and design of 3–D printed fractal triangular antennas will be introduced and investigated. All suggested antennas are evaluated using commercial software. The results assess the good accordance between numerical simulations and experimental validations.
