Problems solved by technology
[0002] At present, the keyless entry system (access control system) and the receiving antenna are composed of three independent antennas wound in three directions in different directions, which occupy a relatively large space, have relatively large installation circuit boards, poor stability and high cost.
Other three-dimensional receiving antennas currently used are relatively large in volume, relatively high in thickness and high in cost, and are not suitable for mass production

Embodiment Construction
[0022] Refer to attached figure 1 , 2 , the three-dimensional low-frequency receiving antenna includes a base 1 , a magnetic core 5 , an X-direction coil 8 , a Y-direction coil 7 and a Z-direction coil 6 . The magnetic core 5 is a sheet magnetic core, rounded corners 9 are arranged at the four corners of the magnetic core, and winding slots 10 are arranged on the four sides of the magnetic core. A positioning protrusion 11 is provided at the lower part of the magnetic core.
[0023] The base 1 is a sheet base, and there are winding grooves 13 on the four sides of the base, and the connecting metal terminals 4 are arranged at the bottom of the four corners 3 of the base. The groove 12 cooperates with the positioning protrusion 11 on the lower part of the magnetic core, so as to facilitate installation and positioning.
[0024] The magnetic core 5 is bonded to the base 1 to form a magnetic core and base assembly, and a coil 8 in the X direction is wound on the X-axis directio...
