A multi-mode 3D-printed conical dielectric resonant antenna (DRA) with a stable omnidirectional pattern is proposed. It covers the band of 1.75-3.64 GHz and 4.96-6.01 GHz. Multiple modes in the conical DRA are effectively excited which are the TM 01δ and TM 03δ modes intrinsic to the dielectric resonator (DR). The combination of probe and sleeve is used to feed the DR to excite additional modes such as the TM 01 and TM 03 modes and the sleeve mode respectively to further extend the bandwidth of the antenna. The sleeve also helps to tune the current distribution of the probe's high-order modes when the DRA is mounted on a finite-size ground plane. The profile of the conical DRA is properly designed to overcome the tilt of the radiation pattern by the ground plane, by which stable omnidirectional radiation patterns are achieved across the whole operating frequency band. The characteristic mode theory and an eigenmode solver are used to verify the numerical analysis. The 3D printing technology is used to fabricate the DRA. Powered LEDs are placed inside the 3D printed DRA to enable its lighting function. The proposed antenna can be fixed on the vehicle's roof for vehicle-to-everything (V2X) communication. It has satisfactory electromagnetic compatibility (EMC) with other vehicle-mounted electronic devices. It is a good candidate for 5G vehicle picocell applications.
