2. Directional antenna - Wikipedia

   en.wikipedia.org/wiki/Directional_antenna

   Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.

3. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   The nulls in the radiation pattern of small receiving loops and ferrite core antennas are bi-directional, and are much sharper than the directions of maximum power of either loop or of linear antennas, and even most beam antennas; the null directionality of small loops is comparable to the maximal directionality of large dish antennas (aperture ...

4. Yagi–Uda antenna - Wikipedia

   en.wikipedia.org/wiki/Yagi–Uda_antenna

   Also called a beam antenna [4] and parasitic array, the Yagi is widely used as a directional antenna on the HF, VHF and UHF bands. [3] [4] It has moderate to high gain of up to 20 dBi, [3] depending on the number of elements used, and a front-to-back ratio of up to 20 dB.

5. Television antenna - Wikipedia

   A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...

6. Log-periodic antenna - Wikipedia

   en.wikipedia.org/wiki/Log-periodic_antenna

   An antenna array consisting of two such antennas, one above the other and driven in phase has a gain of up to 17 dBi. Being log-periodic, the antenna's main characteristics ( radiation pattern , gain, driving point impedance ) are almost constant over its entire frequency range, with the match to a 300 Ω feed line achieving a standing wave ...
