Abstract: An antenna structure is electrically fixed and connected to a main board of an electronic apparatus and includes a circuit board, a high-frequency radiation layer, and a low-frequency radiation layer. The circuit board is a square body with a front surface, a back surface, a top surface, a bottom surface, and two side surfaces. The high-frequency radiation layer is arranged on the front surface of the circuit board and includes a high-frequency coupling edge thereon. The low-frequency radiation layer is arranged on the back surface of the circuit board and includes a low-frequency coupling edge thereon. Moreover, the high-frequency radiation layer and the low-frequency radiation layer fail to overlap with each other. The high-frequency coupling edge and the low-frequency coupling edge couple together to generate a bandwidth of a transmitting-and-receiving frequency of the antenna structure.

Abstract: A vertical antenna structure is electrically fixed and connected to a main board of an electronic apparatus. The vertical antenna structure includes a circuit board, an electrode layer, and a semi-hole electrode layer. The circuit board is a square body with a front surface, a back surface, a top surface, a bottom surface and two side surfaces. The electrode layer is arranged on the front surface and the back surface of the circuit board. The semi-hole electrode layer is arranged on the bottom surface of the circuit board. The semi-hole electrode layer is electrically fixed and connected to the electrode layer. Moreover, the electrode layer and the semi-hole electrode layer are electrically fixed and connected to the main board.

Abstract: An antenna structure electrically fixed on a main board of an electronic apparatus includes a high-frequency-radiation layer, a low-frequency-radiation layer, an electrode layer and a circuit board including a front surface, a back surface, and a notch. The notch allows a left pin and a right pin formed on a lower side of the circuit board. The high-frequency-radiation layer is arranged on the front surface. The low-frequency-radiation layer is arranged on the front surface or the back surface. A coupling gap is formed between the low-frequency-radiation layer and the high-frequency-radiation layer. The electrode layer is arranged on the left pin and the right pin, and electrically connected to the high-frequency-radiation layer and the low-frequency-radiation layer. The antenna structure belongs to the monopole-feed-in-coupling-loop-grounding design. When used in the main boards of different sizes, variation in grounding has a very little effect on the efficiency attenuation of the antenna structure.
