A dielectric embedded antenna for super wideband applications

A dielectric embedded monopole antenna is proposed for super wideband(SWB)applications. The antenna is designed become inverted cone in order to expand the bandwidth, and the SWB antenna possesses a method to minimize the size of antenna by dielectric embedded to lower the height. The antenna is simulated and measured after practically fabricated. Measured results show a good agreement with simulated results that a -10dB bandwidth of 43.5GHz (4.5-48GHz) is achieved with ratio bandwidth 10.7:1.The antenna prototype shows good impedance matching, stable far-field radiation patterns, and constant group delay over the super wideband.
