US 2025/0030167 A1 · ANTENNA STRUCTURE

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.
