Title:
ANTENNA SYSTEM AND RADIO COMMUNICATION EQUIPMENT
Document Type and Number:
Japanese Patent JP3731691
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To allow the antenna system and radio communication equipment to conduct radio communication in an excellent state by avoiding an adverse effect due to fading with a simple configuration.
SOLUTION: Since production of a steady-state dead point is avoided by providing a directivity variable means that changes a directivity of an antenna 10 timewise in the case of sending/receiving a radio wave E1, radio communication is conducted in an excellent state. Thus, the antenna system and radio communication equipment are realized, where adverse effect due to fading is avoided with a simple configuration and radio communication is conducted in an excellent state.
