A Compact 2-18 GHz Halved Vivaldi Antenna
Keywords:
Metal plane, small size, ultra-wide bandwidth antenna, Vivaldi antennaAbstract
A compact, broadband, halved planar Vivaldi antenna has been proposed in this paper. The halved Vivaldi antenna is located on a large metal plane vertically, and connected to the metal plane through feed-line and short-line. The proposed antenna was designed, fabricated, and tested. Experimental and simulated results show that the proposed halved Vivaldi antenna has a wide bandwidth from approximately 1.44 to 18.5 GHz, and a small size of only 30 mm × 60.5 mm. Moreover, the designed antenna can provide excellent characteristics, including directive radiation characteristics and vertically polarized radiation pattern. These results prove that the proposed antenna should be useful in many metal surface-mounted communication systems, such as missile, unmanned aerial vehicles, and the like.
