Metamaterial antenna — This Z antenna tested at the National Institute of Standards and Technology is smaller than a standard antenna with comparable properties. Its high efficiency is derived from the Z element inside the square that acts as a metamaterial, greatly… … Wikipedia
Horn antenna — Pyramidal microwave horn antenna, with a bandwidth of 0.8 to 18 GHz. A coaxial cable feedline attaches to the connector visible at top. This type is called a ridged horn; the curving fins visible inside the mouth of the horn increase the antenna… … Wikipedia
Helical antenna — Helical antennas can operate in one of two principal modes: normal (broadside) mode or axial (or endfire) mode.In the normal mode , the dimensions of the helix are small compared with the wavelength. The far field radiation pattern is similar to… … Wikipedia
