2. Satellite dish - Wikipedia

   en.wikipedia.org/wiki/Satellite_dish

   A new form of omnidirectional satellite antenna, which does not use a directed parabolic dish and can be used on a mobile platform such as a vehicle was announced by the University of Waterloo in 2004. [12] The theoretical gain (directive gain) of a dish increases as the frequency increases. The actual gain depends on many factors including ...

3. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   A 'whip' antenna at the side of a Casio portable TV. Some portable televisions use a whip antenna. [6] This consists of a single telescoping rod about a meter (3.3 feet) long attached to the television, which can be retracted when not in use. It functions as a quarter-wave monopole antenna.

4. Reflective array antenna - Wikipedia

   en.wikipedia.org/wiki/Reflective_array_antenna

   The main lobe of the antenna can be steered electronically within a limited angle by phase shifting the drive signals applied to the individual elements. Each antenna element is fed through a phase shifter which can be controlled digitally, delaying each signal by a successive amount. This causes the wavefronts created by the superposition of ...

5. Parabolic antenna - Wikipedia

   en.wikipedia.org/wiki/Parabolic_antenna

   A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity.

6. Microstrip antenna - Wikipedia

   en.wikipedia.org/wiki/Microstrip_antenna

   A patch antenna is a narrowband, wide-beam antenna fabricated by etching the antenna element pattern in metal trace bonded to an insulating dielectric substrate, such as a printed circuit board, with a continuous metal layer bonded to the opposite side of the substrate which forms a ground plane. Common microstrip antenna shapes are square ...
