Nona‐band, hybrid antenna for metal‐rimmed smartphone applications

Abstract: A new, hybrid, nona‐band antenna of the size 80 × 8 × 5 mm3 is proposed for recent metal‐rimmed smartphone applications. The proposed design is composed of a metallic frame (external antenna) and an internal radiating structure. The proposed antenna is attached to the top part of the smartphone. It uses a microstrip feed as a direct coupling line for the internal radiating structure. The feed also represents a capacitive coupling feed for the overall metal‐rim antenna structure. The metal rim with a small gap … Show more

“…But this design retained a large ground clearance of 15 mm between the system ground plane and the metal frame. In contrast, the designs in [8], [9], [10], [11], [12], [13], [14], [15], [16], [17],…”

“…Inductive coupling, called magnetic excitation in this paper, is always placed at the maximum current position (maximum magnetic field position); electric-magnetic excitation is placed between the maximum and minimum current position; The feeding method mentioned in Section II-B is a magnetic excitation, which can directly feed the metal rim without any matching circuit [2], [3], [6], [17]. When the electric or electricmagnetic feeding method is utilized for metal rim antenna design, an L-shaped feeding line as the excitation is always used to excite the metal rim mode [5], [7], [10], [13], [15], [18]. And it can also be replaced by a capacitor in series with the feeding line, which was used in this paper.…”
