2. Yagi–Uda antenna - Wikipedia

   en.wikipedia.org/wiki/Yagi–Uda_antenna

   A Yagi–Uda antenna, or simply Yagi antenna, is a directional antenna consisting of two or more parallel resonant antenna elements in an end-fire array; [1] these elements are most often metal rods (or discs) acting as half-wave dipoles. [2]

3. Driven and parasitic elements - Wikipedia

   en.wikipedia.org/wiki/Driven_and_parasitic_elements

   Drawing of a Yagi–Uda VHF television antenna used for analog channels 2–4, 54–72 MHz (U.S. channels). It has four parasitic elements: three directors (to left) and one reflector (to right) and one driven element which is a folded dipole (double rod) connected to a 300 Ω twin lead feedline down the mast to the television set.

4. Hidetsugu Yagi - Wikipedia

   en.wikipedia.org/wiki/Hidetsugu_Yagi

   Hidetsugu Yagi (八木 秀次, Yagi Hidetsugu, January 28, 1886 – January 19, 1976) was a Japanese electrical engineer from Osaka, Japan.When working at Tohoku Imperial University, he wrote several articles that introduced a new antenna designed by his assistant Shintaro Uda to the English-speaking world.

5. Log-periodic antenna - Wikipedia

   en.wikipedia.org/wiki/Log-periodic_antenna

   However, a Yagi with the same number of elements as a log-periodic would have far higher gain, as all of those elements are improving the gain of a single driven element. In its use as a television antenna, it was common to combine a log-periodic design for VHF with a Yagi for UHF, with both halves being roughly equal in size.

6. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   Quad antennas are Yagi-Uda antennas made from loops instead of dipoles or monopoles, and are likewise used as a directional antennas on the HF bands for shortwave communication. They are sometimes preferred for longer wavelengths because (if square) they are half as wide as a Yagi built from dipoles and have slightly better directivity.

7. Moxon antenna - Wikipedia

   en.wikipedia.org/wiki/Moxon_antenna

   Layout of Moxon antenna; radiates strongest towards the left. [a] The Moxon antenna design is rectangular, with slightly less than half of the rectangle being the driven element (radiator) and the other part (slightly more than half) being the reflector. It is a two element Yagi-Uda antenna with folded dipole elements, and no director(s).
