“…For the sake of achieve UWB characteristic, different working modes of the hybrid antenna have been excited. The monomeric equilateral triangular DR mode analysis can be found in [30] and [31]. However, all of the analyses are about antennas which are working under TM modes.…”

This paper postulates a novel omnidirectional low-profile ultra-wideband (UWB) antenna, which is structured by discrete embedded dielectric resonator antenna with features of both low-profile dielectric resonator (DR) and thin planar monopole antenna, where the laminated equilateral triangular DR and the rectangular metal patch monopole are stacked up. This new design can lower the profile of the antenna. Furthermore, the symmetric DR and the monopole structure are able to make the surface currents in some operating modes opposite in phase, together with the characteristics of the coplanar waveguide (CPW) feed structure and the DR, the cross-polarization is reduced effectively. The mode analysis has been done to show how the antenna achieves the UWB. The CPW which can integrate with integrated circuits easily is used to provide the excitation source. The antenna provides consistent omnidirectivity, consistent gain, low cross-polarization, and high-radiation efficiency within the entire operation band. A prototype (dimensions are 17.6 mm × 33.6 mm and 1.524 mm thickness) is fabricated and measured. The measurements are well correlated with the simulations. INDEX TERMS Defected ground structure, dielectric resonator, discrete embedded, hybrid antenna, lowprofile, low cross-polarization, omnidirectional, ultra-wideband.
