coaxial antenna

[kō′ak·sē·əl an′ten·ə]
(electromagnetism)
An antenna consisting of a quarter-wave extension of the inner conductor of a coaxial line and a radiating sleeve that is in effect formed by folding back the outer conductor of the coaxial line for a length of approximately a quarter wavelength.

This requires removal (or at least partiallremoval) of the aircraft headliner or overhead panels, cutting a hole, mounting the antenna, sealing the antenna, running coaxial antenna cable from the GPS antenna to the GDL82 and then putting it back together.
The main goal of this work is to validate the double short distance slot coaxial antenna. A computational model, phantom experimentation, and breast swine in vivo experimentation were carried out.
A minimally invasive coaxial antenna was used to irradiate the phantom.
For the next coaxial antenna (antenna 2), a small gap in the outer conductor, spaced a quarter-wavelength back from the end of the coaxial line, is added to the simple extended inner conductor antenna.
This is the type of adapter that kids use to connect their video game machines to the coaxial antenna input of any TV set.
In fact, if you battle performance issues with an existing navcomm, it might make sense to replace antennas first (after bench test) which might also include coaxial antenna cabling.
In addition, RFS Brandon George, Senior Electrical Engineer, will present Advanced Modeling Method for UHF Broadcast Slotted Coaxial Antennas at the Symposiums DTV Repack Session.
These omnidirectional antennas have the advantages of planarity, easy integration and low construction costs, compared to coaxial antennas.
