Abstract
A new fractal like tree structure of circular patch antennas for multi-band and wide-band challenges in 5G technologies is presented in this paper. The elementary structure is shown in Fig. 1. The antenna is designed on low cost Rogers RT/duroid 5880 (tm) substrate fed by a 50-ohm micro-strip line. The antenna is simulated in High Frequency Structure Simulator Software (HFSS). The proposed antenna resonates at five different bands, which makes it a candidate for ultra-wideband (UWB) and 5G systems. The five bands covered by the proposed antenna for a −10 dB return loss are (1.6 GHz–7.5 GHz), (8 GHz–10 GHz), (10.5 GHz–12.2 GHz), (12.7 GHz–16.1 GHz), and the last band (19.3 GHz–23 GHz). The corresponding S 11 response is shown in Fig. 2. Also these bands are achieved with constant radiation pattern characteristics at the different frequency bands.
