摘要： Disclosed is an antenna capable of micro-tuning and macro-tuning for a wireless terminal, comprising: a radiator radiating electromagnetic waves; a ground connected to the radiator; at least one switching element positioned at a lengthwise region of the radiator, for shorting or opening the region of the radiator; and a voltage controlling element positioned at the radiator between the switching element and the ground, for controlling the extent of a voltage potential applied across the radiator. In accordance with the present invention, the antenna is capable of the macro-tuning between the service bands and micro-tuning for channel control within the service bands. Furthermore, the size of the antenna is significantly reduced and the antenna is installed on a circuit board in a patch type, thereby simplifying a work process.

摘要： A mobile terminal and a mobile terminal antenna reduce the intensity of electromagnetic waves radiated in the direction of a human body. The mobile terminal antenna includes a radiator, which radiates electromagnetic waves; a ground which is connected with the radiator, and a radiation preventer which has a metallic bar on one side of the ground in parallel with the ground at an interval. Accordingly, the electromagnetic radiation exposure to the human body can be reduced by altering the radiation emission pattern, while the performance of the antenna can be simultaneously enhanced.
