2. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   Used as base station antennas for land mobile radio systems such as police, fire, ambulance, and taxi dispatchers, and sector antennas for cellular base stations. Curtain array A curtain array is any one of several designs for large, directional, long-distance, broadside transmitting array antennas used at HF by shortwave broadcasting stations.

3. Antenna (radio) - Wikipedia

   en.wikipedia.org/wiki/Antenna_(radio)

   The electric and magnetic fields emanating from a driven antenna element will generally affect the voltages and currents in nearby antennas, antenna elements, or other conductors. This is particularly true when the affected conductor is a resonant element (multiple of half-wavelengths in length) at about the same frequency, as is the case where ...

4. Base station - Wikipedia

   en.wikipedia.org/wiki/Base_station

   The base station is one end of a communications link. The other end is a movable vehicle-mounted radio or walkie-talkie. [6] Examples of base station uses in two-way radio include the dispatch of tow trucks and taxicabs. Basic base station elements used in a remote-controlled installation. Selective calling options such as CTCSS are optional.

5. Cell site - Wikipedia

   en.wikipedia.org/wiki/Cell_site

   Cellular lattice tower A cell tower in Peristeri, Greece. A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network.

6. Slot antenna - Wikipedia

   en.wikipedia.org/wiki/Slot_antenna

   Slotted array UHF television broadcasting antenna. As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an ...
