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.
A minimally invasive coaxial antenna was used to irradiate the phantom.
When the tumor phantom was solid, the glass capillaries and the coaxial antenna were inserted inside the phantom.
The first type of coaxial antenna (antenna 1) was made by simply stripping off the outer conductor to extend the inner conductor by a quarter-wavelength and is shown in Figure 1.
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.
