Embodiment 1

[0020] see figure 1 , a linear RDSS antenna based on the metal frame of the mobile phone, using the metal frame A of the mobile phone and the main board B to form the antenna, the main board is located inside the metal frame of the mobile phone, and the main board also has a part of the antenna structure. RDSS antenna includes L-band antenna and S-band antenna. L-band transmits electromagnetic wave signals of 1610-1625.5Mhz, and S-band transmits electromagnetic wave signals of 2483.5-2500Mhz.

[0021] see figure 1 , Due to the needs of the antenna structure, two insulating clearance areas 1 are provided on one of the short sides of the metal frame of the mobile phone, so that the metal frame of the mobile phone is divided into three parts. The L-band antenna includes an L feeding point 2, an L radiating arm 3 and an L feeding point 4, the L feeding point 2 and the L feeding point 4 are both arranged on the main board, and the L radiating arm 3 includes electrical properties i...

Abstract

The invention discloses a linear RDSS antenna based on a mobile phone metal outer frame, belongs to the technical field of antennas, and solves the technical problem of miniaturization of the RDSS antenna. The technical key point is that the antenna is formed by the mobile phone metal outer frame and a mainboard, wherein the mainboard is located in the mobile phone metal outer frame. The RDSS antenna comprises an L-frequency-band antenna and an S-frequency-band antenna. One short edge of the mobile phone metal outer frame is provided with two insulated clearance areas (1). The L-frequency-bandantenna comprises an L feed point (2), an L radiation arm (3) and an L feed ground point (4), wherein the L feed point (2) and the L feed ground point (4) are both arranged on the mainboard. The S-frequency-band antenna comprises an S feed point (5), an S radiation arm (6) and an S feed ground point (7). The RDSS antenna is applied to the mobile phone.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a linear RDSS antenna based on a metal frame of a mobile phone. Background technique [0002] The Beidou satellite navigation system adopts the integrated system of radio determination satellite (RDSS) and radio navigation satellite (RNSS). . Satellite Radio Determination Service, the full English name is Radio Determination Satellite Service, abbreviated as RDSS. The user-to-satellite distance measurement and position calculation cannot be completed independently by the user, and must be completed by the external system through the user's response. Its characteristic is that through the user's response, when the positioning is completed, the user's position report to the external system is completed, and the integration of positioning and communication can also be realized, and the NAVCOMM integration in the same system can be realized. [0003] Nowadays, people are pursuing...
