Design of a broadband biconically offset fed thick dipole
2005 IEEE Antennas and Propagation Society International Symposium, 2005A parametric study of an offset fed thick dipole excited by a biconical feed section is performed in this paper. Modeling results are obtained using Ansoft's High Frequency Structure Simulator (HFSS) and the Numerical Electromagnetics Code (NEC). It is desired that the dipole has a 10:1 bandwidth performance with return loss better than 10 dB and ...

Comparison of the Impedance Function of Biconical and Bowtie Dipoles
2007 Loughborough Antennas and Propagation Conference, 2007Impedance and admittance functions of simple bicone and bowtie dipole antennas are modelled using rational functions of low order. Results are presented in terms of the poles and residues of the function, which are studied as functions of the flare angle.

The complex antenna factor of broadband, wire-cage biconical dipoles
IEEE International Symposium on Electromagnetic Compatibility, 2003Previous studies on wire-cage biconical dipoles including "calculable" biconical dipoles have considered only the scalar antenna factor. The complex antenna factor (CAF) allows determination of both amplitude and phase information for the incident field and is necessary for the recovery of nonsinusoidal waveforms from measured data.

Theory of biconical and disk-conical dipole antennas
MMET Conference Proceedings. 1998 International Conference on Mathematical Methods in Electromagnetic Theory. MMET 98 (Cat. No.98EX114), 2002Biconical and disk-conical antennas take an important place in the general theory of wide-band antennas. However, in the literature only approximate methods of the solution of integro-differential equations of biconical antennas, which do not enable one to take into account the real geometry of antennas, have been developed. The paper is devoted to the

Design of a Compact Biconical Antenna Loaded With Magnetic Dipoles
IEEE Antennas and Wireless Propagation Letters, 2017A novel compact ultrawideband biconical antenna with the impedance bandwidth of 200-965 MHz for VSWR less than 2.35 is proposed. Two metal disks and cylinders are loaded around a traditional biconical antenna, which can form two magnetic dipoles. The broadband impedance matching, miniaturization, and omnidirectional radiation patterns are achieved ...
