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

and placed in front of the driven element in the intended direction. These parasitic elements are typically off-tuned short-circuited dipole elements...

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...

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

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...

single driven element connected to the transmission line, usually the second one from the back of the array, the remaining elements are parasitic. The Yagi...

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...

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