Title:
ANTENNA SYSTEM
Document Type and Number:
Japanese Patent JPH09307342
Kind Code:
A
Abstract:
To provide a thinest antenna system which can secure a desired radiating level in a low wave angle, a desired operation band and a low reflecting loss.
The thicknesses t1 to tn of each dielectric layer of the antenna system laminating n-number of dielectric layers of a ratio dielectric rate r1 to rn between a base board 10 and a main radiation conductor 9 are fixed so as to almost satisfy (t1+t2+...+tn)/(t1/ri+t2/r2+...+tn/rn)=reff and t1+ t2+...+tn=tmin with respect to the minimum thickness tmin of the dielectric layer securing the desired operation band and the low radiation loss at the ration dielectric rate reff and reff of the antenna fixed from a desired beam width.
