Problems solved by technology
Single-frequency antenna devices are generally not easy to meet people's needs for multi-band wireless communication devices. Existing multi-frequency antennas generally have a more complex structure and a larger volume, and need to be installed at an installation location suitable for transmitting and receiving wireless signals For better sending and receiving effect
However, wireless communication devices are generally small in size, and their internal installation space is very limited, and it is difficult to provide a more spacious installation position suitable for transmitting and receiving wireless signals
Therefore, it is difficult for most of the existing multi-frequency antennas to be directly installed in wireless communication devices to send and receive wireless signals.

Embodiment Construction
[0010] see figure 1 , the multi-frequency antenna 100 of the preferred embodiment of the present invention is a planar antenna that adopts a coplanar waveguide to feed signals. A substrate 300 in the device can transmit and receive radio waves in multiple frequency bands to send and receive radio signals.
[0011] The substrate 300 is a rectangular board, which can be a printed circuit board or a part of the printed circuit board. The substrate 300 includes two first sides 301 parallel to each other and two second sides 302 parallel to each other. The two first sides 301 and the two second sides 302 are vertically connected and form four vertices 303 at the intersections.
[0012] The multi-frequency antenna 100 is disposed on the substrate 300 and includes a radiation unit 10 , a first ground portion 20 , a transmission portion 30 , a second ground portion 40 and a matching circuit portion 50 . The radiation unit 10 , the first grounding portion 20 , the transmission porti...
