AI Technical Summary
Technical Problem
When existing circular polarized antennas achieve high gain and wide beams, they have complex structures and high cost, making it difficult to achieve ideal state at the same time.
Method used
Using a combination of magnetocurrent antennas and current element arrays, feed connections and gap couplings with metal floors through metal patches to form a circularly polarized antenna, simplifying the structure and reducing costs.
Benefits of technology
High gain and wide beams are achieved while achieving ideal state, simplifying structural and assembly difficulty and reducing costs.

Abstract
The invention relates to an antenna and a mobile terminal, the antenna comprises a metal floor, a first dielectric plate and a second dielectric plate which are sequentially arranged from bottom to top in the thickness direction, a gap is formed between the first dielectric plate and the second dielectric plate, a metal patch is arranged on the side, away from the metal floor, of the first dielectric plate, and the metal patch is in feed connection with the metal floor; the metal patch is provided with a gap; the first metal strip is arranged corresponding to the gap, the first metal strip is located on the side, away from the first dielectric plate, of the second dielectric plate, the first metal strip is coupled with the gap of the metal patch, and in the orthographic projection of the first metal strip to the metal patch in the thickness direction, the first metal strip intersects with the corresponding gap; and a non-zero included angle is formed between the length direction of the first metal strip and the extending direction of the gap. According to the antenna and the mobile terminal, high gain and wide beam of the circularly polarized antenna are realized by using the combination of the magnetic current element antenna and the current element array antenna, and the cost is reduced while the structure is simplified.
