Ultra-Wideband Trident Inset-Fed Monopole Antenna With a 3-D Conical Ground

An ultra-wideband antenna with a conical ground and trident inset feeding structure is presented. The consists of U-shaped monopole designed on printed circuit board three-dimensional aluminium mold, serving as the ground. Low frequency (<; 1 GHz) matching achieved feed branches by inserting them into monopole. Simulation studies show that proposed 3-D outperforms horizontal or flat-lying models in terms impedance bandwidth radiation pattern omni-directivity. also helps to stably mount measurement facility. measured results presented this paper demonstrate suitable testing omnidirectional patterns over broad bandwidth. A 14.6:1 ratio (0.56 - 8.2 has been realized at voltage standing wave below 2:1 gain above 2 dBi.
