.~ Having area increasing means (e.g., spiniferous, metal ball on top)
DEFINITION
Classification: 343/899
(under subclass 700) Subject matter wherein the antenna is so formed as to present a larger surface to the radio wave transmitting medium; or wherein additional elements are combined with the antenna for increasing the surface presented to the radio wave propagating medium; or wherein elements are provided which are adapted to be electrically connected to the antenna to increase the surface presented to the radio wave propagating medium.
(1) Note. Examples of this area increasing structure are a spiniferous shaped antenna and a metal mass such as a ball on the free end of a rod type antenna.
