1. A wireless communication device comprising:
a radio-frequency antenna configured as an inverted-F antenna including a first antenna element, a second antenna element, a third antenna element, and a ground plane; and
a plugin port arranged at the first antenna element,
wireless communication circuitry connected to the radio-frequency antenna, the wireless communication circuitry being configured to perform real-time communications of multiple protocols via the radio-frequency antenna,
wherein one end of the first antenna element is connected to the ground plane via the second antenna element, the second antenna element extending along a second side of the inverted-F antenna substantially perpendicular to the first side, and
wherein, at a point between respective ends of the first antenna element, the third antenna element connects the first antenna element to a current feeding unit, the third antenna element extending from the first antenna element to the current feeding unit in a direction substantially parallel to the second side of the inverted-F antenna, the current feeding unit being configured to provide a current to the first antenna element via the third antenna element.
