Low-Profile Cone Antenna with Trapezoidal Plate Element

Small and low-profile antenna is necessary for moving vehicle to communicate various information. However, downsizing of the antenna often reads to deteriorate antenna characteristics. In this paper, we propose small, low-profile and wideband antenna, which consist of cone antenna with simple shaped element. By using electromagnetic simulator, it is verified that proposed antenna has small, low-profile and wideband characteristics.
