Comparison of the Impedance Function of Biconical and Bowtie Dipoles

2007 Loughborough Antennas and Propagation Conference, 2007
Impedance 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.

Design of a broadband biconically offset fed thick dipole

2005 IEEE Antennas and Propagation Society International Symposium, 2005
A 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 ...

The complex antenna factor of broadband, wire-cage biconical dipoles

IEEE International Symposium on Electromagnetic Compatibility, 2003
Previous 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.

Excitation of a slotted bicone by an impulse magnetic dipole

International Conference on Mathematical Methods in Electromagnetic Theory, 2003
An analytical-numerical method for solving three-dimensional electrodynamics boundary problems with unclosed perfectly conducting bicone geometries is proposed. The method is based on using the Laplace transform, the Kontorovich- Lebedev transforms and the dual series regularization approach.

Gain and Antenna Factor Measurements of Broadband Biconical Dipole in the GTEM Cell

2010
The paper presents the method for measuring antenna factor and gain of small antennas in the GTEM cell. In order to investigate the suitability of GTEM cell for this kind of measurement, the measurement results for a biconical dipole with broadband matching balun were compared with those obtained by calibration inside fully absorber lined anechoic site.
