Driven and parasitic elements information

elements. The driven element is often a dipole. The parasitic elements act as resonators and couple electromagnetically with the driven element, and serve...

transmitter. A parasitic array consists of a single driven element connected to the feedline, and other elements which are not, called parasitic elements. It is...

Selfish genetic elements (historically also referred to as selfish genes, ultra-selfish genes, selfish DNA, parasitic DNA and genomic outlaws) are genetic...

free-living, feeding on microorganisms, but there are many that are parasitic. The parasitic worms (helminths) are the cause of soil-transmitted helminthiases...

used on the HF and VHF bands. Like a Yagi–Uda antenna ("Yagi"), a quad consists of a driven element and one or more parasitic elements; however in a quad...

The individual elements are most commonly half wave dipoles, although they sometimes contain parasitic elements as well as driven elements. The reflector...

a simple and mechanically rugged two-element parasitic array, single-frequency antenna. It takes its name from the amateur radio operator and antenna handbook...

reasons. Another difficulty is that there are parasitic capacitances to ground at each node. These parasitic capacitances act as voltage dividers with the...

dipole and points downward 120 degrees from vertical on the opposite side of the support pole from the downward-pointing driven rod. The other elements are...

in.(pp283–371) Parasitic arrays consist of multiple antennas, usually dipoles, with one driven element and the rest parasitic elements, which radiate...

exchanging a directly engine-driven fan for one equipped with a fan clutch or an electric fan. Another modification to reduce parasitic loss, usually seen in...

and resistors are usually designed to minimise other parameters. In many cases this can be done to a sufficient extent that parasitic capacitance and...

insulation, including polyethylene aerogels that reduce solar absorption and parasitic heat gain which may improve the emitter's performance by over 20%. Other...

Delay lines are made of lumped elements of L and C. The parasitic L and the C from the transistors are used for this and usually some L is added to raise...

by the driven element. This time, the phasing is accomplished by careful choice of the lengths as well as positions of the parasitic elements, in order...

through. The drag imposed by the walls of the pipe is somewhat analogous to parasitic resistance. In either model, the pressure difference (voltage) across...

current by inductance and capacitance. Along with resistance, it is one of two elements of impedance; however, while both elements involve transfer of electrical...

called a Seebeck generator, is a solid state device that converts heat (driven by temperature differences) directly into electrical energy through a phenomenon...
