Abstract
An antenna unit has a first antenna operating at wireless telecommunication bands and a second antenna operating at wireless local area network bands. The first antenna has a first radiating conductor with a first feeding point defining opposite sides, a second, a third and a fourth radiating conductors extending from both sides of the first radiating conductor. A parasitic element defines opposite ends. One end of the parasitic element confronts the free end of the third radiating conductor. A trap circuit connects the fourth radiating conductor and the parasitic element. A second antenna has a third side, a fourth side and a stair-shape side. The connection of the sides of the second antenna forms a first protrusion with a second feeding point and a second protrusion confronting the first antenna. A slot is opened on the second antenna. A ground portion is spaced from the first radiating conductor and the first protrusion.
