Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, in particular to a broadband antenna and communication equipment. Background Art

[0002] The mobile phone antenna is a device used to receive signals on the mobile phone. Old mobile phones have protruding antennas, while most new mobile phones have hidden antennas inside the body. This type of antenna is mainly inside the mobile phone, and you cannot see what is inside from the appearance of the mobile phone. The bandwidth of the antenna is an important parameter to describe the performance of the antenna. It refers to the frequency range in which the antenna can operate while maintaining specific electrical parameters (such as impedance and directivity). This range can be from the lowest operating frequency to the highest operating frequency. However, in the case that existing products are all designed towards miniaturization and the application environment is complex, there is not enough space to set up multiple antenna structures, resulting in the inability to meet the bandwidth requirements of full-band performance. Utility Model Content

[0003] Based on this, it is necessary to provide a broadband antenna and communication equipment to address the problem that existing antennas cannot meet the requirements of the full frequency band due to space limitations.

[0009] A third radiating portion, as a parasitic body coupled to the main end of the broadband antenna, is used to generate intermediate frequency resonance;

[0010] A low-frequency coupling slot is provided between the feeding point and the feeding ground point, and is used to generate a low-frequency bandwidth;

[0011] A high-frequency coupling slot is provided next to the feeding point to generate a high-frequency bandwidth.

[0012] A parasitic unit is arranged in a second direction of the feeding point.

[0013] On the other hand, the utility model also provides a communication device, comprising the broadband antenna as described above.
