Title:
ANTENNA MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/013650
Kind Code:
A1
Abstract:
This antenna member has an injection molded body formed from a thermoplastic resin composition and is used by metal-coating at least a portion of the injection molded body. The thermoplastic resin composition contains a polyphenylene ether-based resin. The thermoplastic resin composition has a load deflection temperature of at least 120°C. When increasing the temperature of the thermoplastic resin composition in a range from -30°C to 120°C, said range is divided into 10°C-temperature ranges, and, between two of the temperature ranges adjacent to each other, the low temperature side is defined as a low-temperature range and the high temperature side is defined as a high-temperature range. A low-temperature range expansion coefficient and a high-temperature range expansion coefficient for any two of the adjacent temperature ranges, as measured by a method according to ISO 11359, satisfy the following relationship: -50 ≤ ((high-temperature range expansion coefficient - low-temperature range expansion coefficient) / low-temperature range expansion coefficient) × 100 ≤ 50.
