Title:
ANTENNA MODULE
Document Type and Number:
WIPO Patent Application WO/2019/167534
Kind Code:
A1
Abstract:
The present invention suppresses deviation of the characteristics of an antenna module from the desired characteristics. An antenna module (100) according to the present invention transmits and receives high frequency signals. A first ground electrode (141) and a second ground electrode (142) are arranged to face each other. A plurality of via conductors (150) connect the first ground electrode (141) and the second ground electrode (142) to each other. A first antenna element (1111) is arranged on the opposite side of the plurality of via conductors (150) with respect to the first ground electrode (141). A first high frequency element (190) is arranged between the first ground electrode (141) and the second ground electrode (142). The first high frequency element (190) supplies electric power to the first antenna element (1111). The distance between the first ground electrode (141) and the second ground electrode (142) is shorter than a half of the effective wavelength of high frequency signals between the first ground electrode (141) and the second ground electrode (142).
