Low-Profile Wideband Antenna by Loading Oblique Short Elements to Trapezoidal Plate with Capacitance Disk

抄録

This paper proposes a low-profile wideband antenna composed of a capacitance disk, trapezoidal plate, and four oblique short elements. The characteristics of the proposed antenna are analyzed through simulation. The results demonstrate that the proposed antenna offers a low-profile and wideband performance. In addition, its radiation patterns are omnidirectional in horizontal plane. This antenna is prototyped, and the validity of the simulation is verified through measurements.
