The article presents a wideband hemispherical dielectric resonator antenna (DRA) designed for 20 to 28 GHz, addressing alignment challenges through three innovative methods: outlining the DRA position, using a grooved ground plane, and 3D-printing on a perforated substrate. The DRA achieves a 33.33% impedance bandwidth and a maximum gain of 10 dBi, with experimental results closely matching simulations. These simple alignment techniques significantly reduce assembly time and improve measurement accuracy for
