For　the　first　time,　a　MgAl2O4　transparent　ceramic　cylindrical　dielectric　resonator　antenna　(DRA)　is　designed　using　the　fundamental　HE11δ　modes　for　slot　excitation.　The　transparent　microwave　dielectric　ceramic　was　synthesized　using　high-purity　MgO　and　γ-Al2O3　powders　by　aqueous　gel-casting　combined　with　cold　isostatic　pressing,　pressure-less　sintering　and　hot　isostatic　pressing　methods.　Optimum　relative　permittivity　∼8.2,　Q　×　f　(Q　=　quality　factor　=　1/dielectric　loss,　f　=　resonant　frequency)　∼110 510　GHz　and　temperature　coefficient　of　resonant　frequency　∼-74.1　ppm　°C-1　were　obtained.　The　reflection　coefficient,　the　input　impedance,　the　antenna　gain　and　the　radiation　pattern　of　the　transparent　cylindrical　ceramic　DRA　were　examined,　and　it　was　observed　that　the　simulation　results　were　in　reasonable　agreement　with　the　measurement　results.　It　has　been　found　that　the　proposed　transparent　cylindrical　MgAl2O4　ceramic　DRA　can　provide　a　higher　impedance　bandwidth　(BW　=　735　MHz)　and　radiation　efficiency　(95.8%)　than　a　state-of-the-art　transparent　glass　DRA.　The　proposed　configuration　can　potentially　be　used　for　such　useful　antenna　decoration　and　can　be　used　as　a　lampshade　to　integrate　these　antennas　in　street　and　traffic　lights　without　compromising　the　aesthetics　of　the　city.　This　journal　is　©　The　Royal　Society　of　Chemistry.
