Dual-band dual-port antenna structure

A dual-band dual-port antenna structure, comprising:

• a first antenna structure and a second antenna structure;
• wherein the first antenna structure operates in a high-frequency band and comprises a first feeding port, a first feeding path electrically connected to the first feeding port, and a first radiating element;
• the second antenna structure operates in a low-frequency band and comprises a second feeding port, a second feeding path electrically connected to the second feeding port, and a second radiating element;
• the first feeding path comprises a first capacitor and a first feeding line;
• the second radiating element comprises a first radiation branch and a second radiation branch;
• the first radiation branch comprises a first inductor and the second radiation branch comprises a second inductor;
• and
• the second radiating element of the second antenna structure at least partially surrounds the first radiating element of the first antenna structure.
