Title:
ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2001/045208
Kind Code:
A1
Abstract:
An antenna device provided with a matching circuit (4) for accommodating reflection coefficients of antenna elements (1a, 1b, 1c, 1d), the reflection coefficients being defined in consideration of connections among the antenna elements (1a, 1b, 1c, 1d) when each of the antenna elements is excited according to an excitation frequency and excitation phase corresponding to each frequency in operation.
