Nc. Yuan et al., A NEW-TYPE OF ULTRA-WIDE-BAND CONICAL ANTENNA RIDGED WITH A NOVEL FINLINE RADIATOR, International journal of infrared and millimeter waves, 19(2), 1998, pp. 343-347
A new type of ultra-wide band(UWB) conical antennas ridged by a novel
taper finline radiator(TFR) used as radiation and receiving of the sho
rt pulse are developed. In which, a new UWB feed structure of a coplan
ar waveguide to finline and a TFR ridge are used initially. The experi
ment results show the characteristics of high fidelity, high efficienc
y, and high gain compared with some common broad-band antennas such as
the biconical antennas, V-conical antennas, logarithm periodic antenn
as, and the other TEM horns.
