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.

Characteristics of biconical microstrip antennas
Antennas and Propagation Society Symposium 1991 Digest, 2002Characteristics of biconical microstrip antennas asymmetrically excited by a coaxial probe feed are studied. The antenna consists of a conducting cone cap on a grounded cone separated by an electrically thin dielectric. A study of the theta -dependent eigenvalues nu of the spherical wave functions in the omega direction has shown that there is a unique

Analysis of biconical microstrip antennas
IEE Proceedings H Microwaves, Antennas and Propagation, 1992Biconical microstrip antennas having a conical patch over a conical substrate are investigated. Analytical expressions for the field distribution inside the conical cavity are developed in a spherical coordinate system and used to determine the eigenvalues of the resonant modes. It is found that, in addition to the axially symmetric modes, TE modes can

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.

Characterization of biconical transmitting antennas
Radio Science, 1991We have obtained a general, numerical solution of an ideal biconical transmitting antenna, with arbitrary arm length and conic angle. The solution evaluates the field coefficients associated with the electric multipolar expansion terms both within the antenna region and external to it; the set must necessarily be truncated, and we truncate our set with

Calculable antenna factor of a biconical reference antenna
2011 IEEE International RF & Microwave Conference, 2011Calculable antenna is used as a reference antenna for antenna calibration to obtain accurate antenna factor. This paper focuses on calculable biconical antenna with low uncertainty. The proposed biconical antenna factor can be derived either by simulation or by analytical method. The antenna factor is directly derived from antenna gain.

Direct feed biconical antenna as a reference antenna
2011 IEEE International RF & Microwave Conference, 2011Antenna factor is the main parameter in EMC measurement. Therefore, accurate and low uncertainty antenna is important in order to gain a reliable antenna factor. Direct feed biconical antenna has low uncertainty because balun can be eliminated in the design. Furthermore, the biconical antenna has fix phase center.

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 ...

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 ...
