Analysis of transmitting wire antenna

2012 International Conference on Power, Signals, Controls and Computation, 2012
Researches and investigations in transmitting wire antenna is continuing. The term wire means metallic, highly conducting, solid or tubular electrically thin wires, i.e. wires with diameter very small compared to the length of the wire and the wavelength of an incident plane wave.

Active Tongue Pulsed Transmitting Antenna

2006 3rd International Conference on Ultrawideband and Ultrashort Impulse Signals, 2006
A novel, UWB, pulsed, active, and transmitting antenna is proposed, which is based on the authors' developed and patented UWB antenna design concept called the tongue antenna. This antenna can be directly driven by a pulser circuit with a ferrite ring transformer which contributes to about 30% extra pulse peak amplitude.

Characterization of biconical transmitting antennas

Radio Science, 1991
We 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

Massive MIMO Antenna Transmitting Characterization

2018 IEEE MTT-S International Microwave Workshop Series on 5G Hardware and System Technologies (IMWS-5G), 2018
In this work a Massive MIMO antenna transmitting characterization system is proposed to study couplers effects between antenna arrays elements, using software defined radio and LabVIEW. In this sense, a calibrated measurement MIMO system will described, by using a SOL procedure and a power meter to have a precise magnitude. In addition, an architecture

The Thick Tubular Transmitting Antenna

Radio Science, 1967
The growing importance of electrically thick monopole antennas has suggested a re‐examination of the model used in the derivation of the integral equation for the current in tubular antennas. It is shown that when such an antenna is driven from a coaxial line in the usual manner, which maintains a field along a narrow circumferential region on the ...

Multilayer Antenna-Filter Antenna for Beam-Steering Transmit-Array Applications

IEEE Transactions on Microwave Theory and Techniques, 2012
This paper presents a study on reconfigurable transmit-array (TA) antennas based on multilayer tunable elements. The proposed configuration can be referred to as a multilayer antenna-filter antenna (MAFA) and it can be viewed as an extension of the antenna-filter antenna concept.

Direct Transmit Antenna Selection for Transmit Optimized Spatial Modulation

2013 IEEE 78th Vehicular Technology Conference (VTC Fall), 2013
To improve the performance of spatial modulation (SM) over correlated MIMO channels, transmit optimized spatial modulation (TOSM) has been proposed recently. It trades off traditional signal constellation diagrams with spatial constellation diagrams to minimize the average bit error probability (ABEP).

Compact Push-Pull Active Integrated Transmitting Antenna

The European Conference on Wireless Technology, 2005., 2005
In this paper, a novel method of spatially coupling differential signals to an antenna structure is described. A differential signal is used to generate a current maximum/virtual short circuit under the antenna and electromagnetic energy is efficiently coupled from the transmission line to the antenna via an aperture.

TV Transmitting Antenna Selection

IEEE Transactions on Broadcasting, 1969
In the selection of a transmitting antenna, factors such as power gain, height above terrain, horizontal pattern directivity, amount of null fill, and beam tilt of the vertical pattern have to be taken into consideration to best satisfy the equipment availability and intended market coverage.
