Title:
ANTENNA ASSEMBLY
Document Type and Number:
Japanese Patent JP2005057438
Kind Code:
A
Abstract:
To realize an excellent frequency characteristic and signal reproducibility by suppressing an influence of reflection at an element end of an antenna having a conical or triangular element.
Slits 31 to 35 are formed in the periphery of the end at a distance from a feed point 4 of the conical or triangular antenna element 2 to obtain capacitive coupling and then its degree of coupling is gradually decreased to enable slow termination. Consequently, abrupt reflection of a signal at a terminal end is suppressed.
