High Gain and Dual Band SIW-Fed Stacked Conical DRA for 5G NR FR1 Application

This work presents a high gain and dual band slotted Substrate Integrated Waveguide (SIW) fed Dielectric Resonator Antenna(DRA). In this study, integrating both these technologies, an antenna with high gain and dual bandwidth is proposed. A stacked conical DRA structure is placed on SIW to attain high gain. A superstrate is placed above the stacked conical DRA to increase the antenna's directivity. The simulation result shows that the proposed antenna can operate for dual-band with the bandwidth of 210 MHz (5.24 - 5.45 GHz) and 60 MHz (6.10 - 6.16 GHz). This antenna is linearly polarized and shows a peak total gain of 9.62 dBi. The co-polarization and cross-polarization differences are above 50 dB for the E-plane and H-plane. The DRA is fabricated using 3D printing. The measurements are done for antenna prototype. It is suitable for 5G New Radio (NR) Frequency Range 1 (FR1) n46 and n96 bands.
