2. J-pole antenna - Wikipedia

   en.wikipedia.org/wiki/J-pole_antenna

   The J-pole antenna is an end-fed omnidirectional half-wave antenna that is matched to the feedline by a shorted quarter-wave parallel transmission line stub. [5] [1] [6] For a transmitting antenna to operate efficiently, absorbing all the power provided by its feedline, the antenna must be impedance matched to the line; it must have a resistance equal to the feedline's characteristic impedance.

   English: Diagram of a J-pole antenna, a vertical end-fed half-wave omnidirectional transmitting antenna used in the shortwave frequency bands. It consists of a vertical element a half wavelength (/) long, fed in series with a quarter wavelength (/) transmission line stub, with the coaxial cable feedline (F) from the transmitter attached along the stub.

   The diagram shows the standing waves of voltage (V, red bands) and current (I, blue bands) on the antenna elements. It consists of a vertical element a half wavelength ( λ / 2 {\displaystyle \lambda /2} ) long, fed in series with a quarter wavelength ( λ / 4 {\displaystyle \lambda /4} ) transmission line stub , with the parallel wire feedline ...

   A horn antenna has a flaring metal horn attached to a waveguide. It is a simple antenna with moderate gain of 15 to 25 dBi, used for applications such as radar guns, radiometers, and as feed antennas for parabolic dishes. Slot Consists of a waveguide with one or more slots cut in it to emit the microwaves. Linear slot antennas emit narrow fan ...
