Title:
ANTENNA AND RADIO WAVE TRANSMISSION METHOD
Document Type and Number:
Japanese Patent JP2015177340
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that, in an antenna for transmitting a radio wave, downsizing and reduction in weight are difficult.SOLUTION: The antenna includes: a radiator for isotropically radiating a radio wave of a predetermined wavelength; a first modulation element which outputs the radio wave after modulating its radiation direction in a predetermined cycle; a shortening body for propagating the radio wave outputted by the first modulation element with a wavelength shorter than the predetermined wavelength: and a second modulation element for outputting the radio wave passed through the shortening body after modulating its radiation direction in a cycle different from the modulation cycle of the first modulation element.
