Material Properties Influencing BaTiO‑ Dielectric Resonator Antenna at 2.5 GHz
Dielectric resonator antennas (DRAs) rely heavily on material permittivity and loss tangent to define resonance, bandwidth, and efficiency. BaTiO? is a high-permittivity ceramic, ideal for compact DRAs. HFSS simulations must incorporate accurate εr and tanδ values. The shape, feed type, and fabrication tolerances further affect antenna Q-factor and bandwidth.
