Title:
COIL ANTENNA BASE PLATE UNIT FOR HIGH-FREQUENCY USE
Document Type and Number:
WIPO Patent Application WO/2011/004857
Kind Code:
A1
Abstract:
The disclosed device inhibits wavelength reduction and losses in antenna gain, which are caused by a base plate. In a coil antenna base plate unit for high-frequency use, a high-frequency coil antenna (1) is mounted onto a base plate (11) and through-holes (12a, 12b) are provided in the base plate (11) in the area directly below the coils (1a, 1b) of the high-frequency coil antenna (1). There is no dielectric material in the base plate (11) because the area directly below the coils (1a,1b) of the high-frequency coil antenna (1) consists of the through-holes (12a, 12b), enabling the inhibition of the effect of dielectric loss and the inhibition of wavelength reduction and losses in antenna gain, caused by the base plate (11).
