Title:
ANTENNA MODULE AND COMMUNICATION DEVICE HAVING SAME MOUNTED THEREON
Document Type and Number:
WIPO Patent Application WO/2021/131283
Kind Code:
A1
Abstract:
An antenna module (100) comprises: radiation elements (131, 132) that radiate radio waves of a first polarization direction; and a feeding wire (150) that supplies a common high frequency signal to the radiation elements (131, 132). The radiation element (131) and the radiation element (132) are adjacently arranged. The feeding wire (150) includes a common wire (153) and wires (151, 152) branching from the common wire (153). The wires (151, 152) are coupled to the radiation elements (131, 132), respectively. When the radiation elements (131, 132) are seen from a branching point (BP) of the feeding wire (150), the frequency characteristic of the impedance of the radiation element (131) is different from the frequency characteristic of the impedance of the radiation element (132). In a case where a frequency band for which the reflection loss in each radiation element is equal to or less than a predetermined value is defined as an operatable bandwidth, the operatable bandwidth of the radiation element (131) and the operatable bandwidth of the radiation element (132) partially overlap.
