Abstract

We propose a miniaturized triple band printed monopole antenna for 5G, WLAN, WiMAX and X-band applications. Slots are etched in a printed rectangular monopole to design the antenna. A slot etched in a rectangular monopole increases the capacitance and therefore, decreases the resonant frequency or miniaturizes the antenna. Slots in a rectangular monopole antenna also create different current path lengths which resonates at different frequencies. Three slots are etched, and parameters are optimized to achieve triple bands to operate over 5G (3.3 to 3.6 GHz), WiMAX (3.4 to 3.6 GHz), WLAN (5.725-5.875 GHz), WLAN 5.9 GHz band (5.850-5.925 GHz) and X-band (7.3-7.9). The lower 45 MHz (5.850-5.925 GHz), and upper 30 MHz (5.895-5.925 GHz) of WLAN band also find applications for automobile safety in Cellular Vehicle-to-Everything (C-V2X) technology. The radiation patterns are nearly omnidirectional. The antenna is fabricated on a 0.154λ₀×0.143λ₀ board area, where λ₀ is the free-space wavelength at 3.3 GHz. The measured results are in close agreement with the simulation ones.
