An Ultra-Wideband Bicone Antenna
2006 IEEE International Conference on Ultra-Wideband, 2006An ultra-wideband bicone antenna is developed to cover the 25 MHz to 6 GHz frequency band with a minimum gain at the horizon greater than -5 dBi (>100 MHz) to -10 dBi (25-100 MHz) over this frequency range and a VSWR falling between 2:1 and 3:1. This bicone has a radiating aperture that is 2 inches in diameter and 44 inches long.

On the impedance of a class of biconical antennas
IEEE Transactions on Antennas and Propagation, 1969It is shown that the results derived in a series of papers by K, Franz in general represent upper bounds rather than exact expressions for the impedance characteristics of a class of dipole antennas with biconical input regions.

Design of a compact biconical antenna for UWB applications
2011 International Symposium on Intelligent Signal Processing and Communications Systems (ISPACS), 2011This paper presents the study, design, fabrication, and measurement of a vertically polarized compact biconical antenna that can be used as a reference antenna. The study from simulation results suggest that the optimal antenna shall have the flare angle of 60° which gave the most stable vertical beamwidth in the broadside direction and the fewest ...

Calibration of biconical antennas using the standard antenna method
1999 International Symposium on Electromagnetic Compatibility (IEEE Cat. No.99EX147), 2003Antenna arrangements for calibration of EMI biconical antennas are theoretically investigated using the method of moments. It is found that, below the resonance frequency around 70 MHz of a biconical antenna, the standard antenna method yields antenna factors monotonously approaching a far-field value with increasing the antenna separation distance.

Some design considerations for biconical antennas
1984 Antennas and Propagation Society International Symposium, 2005This paper discusses the use of the body of revolution moment method formulation to predict the radiation patterns of biconical antennas, and describes a novel and practical feed point arrangement for fine-tuning the antenna reflection coefficient.

Analysis of linear biconical antenna array
2010 INTERNATIONAL CONFERENCE ON COMMUNICATION CONTROL AND COMPUTING TECHNOLOGIES, 2010The biconical dipole antenna is frequency independent antenna. A dipole antenna is a narrowband and frequency dependent. In this paper a linear array of five biconical antennas with cone angle 30° is modeled in WIPL-D software and analyzed. Radiation pattern, gain, impedance and S- parameter plots of the array are analyzed and presented for 1–5 GHz ...

Modified Biconical Antenna for Ultrawideband Applications
2016 10th European Conference on Antennas and Propagation (EuCAP), 2016In this paper a compact antenna for ultrawideband applications is presented. The antenna is based on the biconical antenna design and has two identical elements. Each element is composed of a cone extended with a ring and an inner cylinder. The modification of the well-known biconical structure is made in order to reduce the influence of the radiation ...

Interaction Between Thin Biconical Antennas
Measurement Techniques, 2017Formulas for estimating the error in measurement of the electric field strength caused by interaction between the generating and measuring antennas are obtained. Thin biconical antennas and different modes of operation of the generating antenna are considered.

Time-domain three antenna method for biconical antenna
CPEM 2010, 2010We apply our proposed method [1] for evaluating the free-space antenna factor of a Biconical antenna. The method is based on the techniques of a time domain analysis and a pulse compression technique. The method enables us to isolate the direct wave from the reflected waves on the ground plane in an open area test site, and to evaluate the free-space ...
