1. An antenna assembly with compact layout traces, wherein the antenna assembly is applicable to a multi-input multi-output (MIMO) system-based product, the antenna assembly comprising:

  • a circuit board provided with a low-frequency module and a high-frequency module;

    at least one low-frequency antenna unit located at an edge of the circuit board and electrically connected to the low-frequency module, wherein the low-frequency antenna unit is composed of a first low-frequency antenna of a planar inverted-F antenna (PIFA) structure, a second low-frequency antenna of the PIFA structure, and a low-frequency neutralization line;

    the first low-frequency antenna and the second low-frequency antenna are spaced apart from each other;

    the low-frequency neutralization line has two ends corresponding respectively to the first low-frequency antenna and the second low-frequency antenna in an overlapping manner; and

    the two ends of the low-frequency neutralization line are electrically connected to the first low-frequency antenna and the second low-frequency antenna respectively; and

    at least one high-frequency antenna unit located at another edge of the circuit board and electrically connected to the high-frequency module, wherein the high-frequency antenna unit is composed of a first high-frequency antenna of the PIFA structure, a second high-frequency antenna of the PIFA structure, and a high-frequency neutralization line;

    the first high-frequency antenna and the second high-frequency antenna are spaced apart from each other;

    the high-frequency neutralization line has two ends corresponding respectively to the first high-frequency antenna and the second high-frequency antenna in an overlapping manner; and

    the two ends of the high-frequency neutralization line are electrically connected to the first high-frequency antenna and the second high-frequency antenna respectively.
