✦ Synopsis

A new wideband antenna employing a shorted bowtie patch for exciting a slot-type radiation is presented. Unlike a conventional directional slot antenna, which generally is placed 1/4wavelength above a ground reflector, the height of the proposed antenna is 1/10-wavelength but a directional radiation can be achieved. The impedance bandwidth is 64% (SWR Յ 2) from frequency of 2.07 to 4.02 GHz. The antenna does not only have a wideband feature but also has several attractive electrical characteristics such as symmetric radiation pattern, low cross polarization and stable pattern over the operating bandwidth.

## Abstract We propose a novel bowtie radar antenna with a pyramidal reflector, which shows low return loss and high directional gain, capable of covering the whole ultra wideband (UWB) frequency band. The measured return loss is less than −10 dB over 3.0–11.7 GHz, and the radiation pattern is unid

## Abstract In this paper, a novel design procedure for designing a compact UWB antipodal Vivaldi antenna is presented. The antenna operates over the UWB frequency band from 3.1 to more than 10.6 GHz. Its measured far‐field radiation is directive and its peak gain is 10.2 dBi in the specified band.
