An antenna structure includes a connection portion. A feed portion connecting to the connection portion defines a feed point thereon. An inductance portion extends from the connection portion, and a free end of the inductance portion connects to a ground end. A capacitance portion that is in a long narrow strip shape extends from the connection portion and is parallel with and adjacent to the ground end. And radiating portions connect to the connection portion respectively. The antenna structure employs the inductance portion, the capacitance portion and the ground end to simulate a LC parallel connection to substitute for an inductor and a capacitor. Therefore, the antenna structure achieves an aim of adjusting a resonance frequency and an impedance matching without the inductor and the capacitor, simplifying the design of the antenna structure, decreasing the manufacture cost and attaining a good performance.

An antenna includes a first radiating conductor and a second radiating conductor. The first radiating conductor defines a first edge, a second edge and a lateral edge connecting the first edge and the second edge. The second radiating conductor has a main body spaced away from the second edge and connected to an end of the first radiating conductor far away from the lateral edge by a first connecting portion and extending towards the lateral edge. A free end of the main body bends to the second edge to form a second connecting portion spaced away from the lateral edge. A radiating end bends oppositely to the first radiating conductor from an end of the second connecting portion and is adjacent to the second edge. A feeding conductor and a grounding conductor are connected to an edge of the first radiating conductor different from the first edge and the lateral edge.
