Perpendicular to this is the vector of tangential speed. The tangential speed has an effect on the antenna control of target tracking radars. If an airplane flies past on a straight course at radar set, it comes to a point, the radial speed is zero here and the tangential speed is equal for the true speed of the airplane.

Log periodic antenna types & variants Er zijn verschillende vormen van log periodieke antenne. Het exacte type dat het meest van toepassing is voor een bepaalde toepassing, is afhankelijk van de vereisten. De belangrijkste typen log periodieke antenne omvatten: Log periodic dipole array, LPDA; Slot log periodic; Zig zag log periodic array 본 논문은 내부 칸막이(diaphragm) 구조를 갖는 38 GHz용 도파관 슬롯 16$\times $16 배열 안테나의 설계와 측정결과를 보여준다. 우선, 도파관 윗면에 전파 진행  A planar slotted waveguide array antenna has been designed at 9.37 GHz for X- band radar applications.

A low-cost Ku-band array of microstrip antennas, which is fed by standard waveguide, is presented in this paper. The 72 corner-fed square patches of the array are arranged in a 6-by-12 configuration.

Linearly polarized arrays are also provided by changing slot array arrangement. The feeding structures are given by a coaxial probe and cavity resonators, which is presented in detail. The applications of radial line slot antennas are satellite communication antenna, plasma etching, and high power use. 22. A flat, radial line slot antenna having a radial waveguide including a front plate and a rear plate, the front plate being provided with an array of radiating slots formed therein and an array of reflection cancelling slots formed in the rear plate, wherein the radiating slots in the front plate are arranged in an annular pattern and form concentric rings of slots in the front plate.

In the slot (3) are arranged a number of slot antennas incorporating elongated radiating areas (4,5) extending along the length of the slot (3) the geometric forms of which are bounded by an HF-conductive frame incorporating at least one ground edge conductor (1,6, 7) and one signal edge conductor (2, 8, 9) and at least one terminating

Er zijn 164 magnetische loop antenne leveranciers, vooral gevestigd in East Asia. De belangrijkste leverancierslanden of -regio's zijn china, italië, die respectievelijk 98%, 1% voorzien van magnetische loop antenne. Magnetische loop antenne-producten zijn het populairst in North America, Domestic Marketen South America. equalization to the signals acquired from an array of antennas in a RADAR system, with each element of the array feeding a separate input channel to a DSP with a high bandwidth link to the FPGA. • The data stream from the sensor to the FPGA in EO/IR applications can be overwhelming for data management and Sluit een antenne en aarde aan de 2wnd loop en een diode met koptelefoon aan de getunde kant zodat je leuke kristal set hebt. Of als de sterkte van het station echt sterk is dan sluit je de 2wnd loop gewoon niet aan. Gebruik de ongetunde winding als terugkoppelspoel in een regenerative set. Gebruik alleen de grote loop zonder tuning C naar je

Windom-antenne: wordt op ong. één derde van het einde gevoed met open voedingslijn - maar elke experimenterende amateur vermeldt andere optimale afmetingen ! Tegenwoordig worden deze antennes - in een moderne versie ook wel OCF ( "Off center fed dipole" ) genoemd - vaak met een coaxkabel en een 1/6 balun gevoed, want de impedantie in het
