  2. Yagi–Uda antenna - Wikipedia

    en.wikipedia.org/wiki/YagiUda_antenna

    A YagiUda 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. Hidetsugu Yagi - Wikipedia

    en.wikipedia.org/wiki/Hidetsugu_Yagi

    A three-element YagiUda antenna used for amateur radio.The longer reflector element (left), the driven element (center), and the shorter director (right) each have a so-called trap (parallel LC circuit) inserted along their conductors on each side, allowing the antenna to be used at two different frequency bands.

  4. Quad antenna - Wikipedia

    en.wikipedia.org/wiki/Quad_antenna

    A quad antenna is a type of directional wire radio antenna used on the HF and VHF bands. A quad is a YagiUda antenna ("Yagi") made from loop elements instead of dipoles: It consists of a driven element and one or more parasitic elements; however in a quad, each of the loop elements may be square, round

  5. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    A VHF/UHF antenna combines two antennas feeding the same feedline mounted on the same support boom. More extended elements that pick up VHF frequencies are located at the back of the boom and often function as a log-periodic antenna. Shorter elements that receive the UHF stations are located at the front of the boom and often function as a Yagi ...

  6. Driven and parasitic elements - Wikipedia

    en.wikipedia.org/wiki/Driven_and_parasitic_elements

    The parasitic elements in a Yagi antenna are mounted parallel to the driven element, with all the elements usually in a line perpendicular to the direction of radiation of the antenna. What effect a parasitic element has on the radiation pattern depends both on its separation from the next element, and on its length.

    Also called a Moxon rectangle; it is a rectangular-shaped, folded version of a two-element Yagi-Uda, hence a minimal parasitic array. [14] Quad Although "quad" can refer to a single quadrilateral-shaped loop, the term usually refers to two or more loops stacked side by side as a parasitic array; at first glance, quads resemble a box kite frame.

  9. 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).
