A Semi-Angular Cylindrical Shape-Based Wideband Circularly Polarized Dielectric Resonator Antenna for C-V2X and Sub-6 GHz IoT Applications
This article highlights the realization of a circularly polarized (CP) dielectric resonator antenna (DRA) that consists of two orthogonally placed aperture-coupled semi-angular cylindrical DRs and has 45.1% of wide axial ratio bandwidth (ARBW). The antenna has an acceptable axial ratio value (<in...

| Summary: | This article highlights the realization of a circularly polarized (CP) dielectric resonator antenna (DRA) that consists of two orthogonally placed aperture-coupled semi-angular cylindrical DRs and has 45.1% of wide axial ratio bandwidth (ARBW). The antenna has an acceptable axial ratio value (<inline-formula> <tex-math notation="LaTeX">$\leq 3$ </tex-math></inline-formula>dB) and impedance bandwidth (<inline-formula> <tex-math notation="LaTeX">$S_{11} \leq -10$ </tex-math></inline-formula> dB) from 3.18-5.02 GHz that covers n77, n78, n48, and n79 5G bands. Additionally, it supports wireless standards that are essential for next-generation sub-6GHz Internet of Things (IoT) communications, such as WiMAX (3.3-3.8 GHz), Citizens Broadband Radio Service (CBRS) (3.55-3.7 GHz), and LTE (uplink 3.41-3.5 GHz/downlink 3.51-3.6 GHz). The antenna shows consistent broadside radiation with a cross-polarization discrimination (XPD) <inline-formula> <tex-math notation="LaTeX">$\geq 15$ </tex-math></inline-formula> dB throughout the band with a maximum gain value of 6.3 dBic at 3.4 GHz. It has a volume of <inline-formula> <tex-math notation="LaTeX">$1.4\lambda _{0} \times 1.4\lambda _{0} \times 0.1\lambda _{0}$ </tex-math></inline-formula> (at lower frequency) and can be a good candidate for the emerging C-V2X (Cellular Vehicle-to-Everything) which mainly uses 5G NR (3.3-4.2 GHz (C-Band, mid-band 5G for wide-area coverage) along with LTE 4G and 4.9 GHz (Public Safety Band) for its communication. |
