Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and fig. 2, the antenna with switchable antenna feeding points of the present invention includes an antenna 1, the antenna 1 is a metal antenna, at least two antenna feeding points 2 are disposed on the surface of the antenna 1, the antenna feeding points 2 are connected to the radio frequency front end through an antenna switch to realize switching of the two antenna feeding points 2, and at least one grounded point 3 is further disposed on the surface of the antenna 1.
The rf front end includes a transmitting path and a receiving path, which is prior art and will not be described in detail herein.
Preferably, the antenna feeding points 2 are two, respectively a first antenna feeding point 4 and a second antenna feeding point 5, and the first antenna feeding point 4 and the second antenna feeding point 5 are respectively connected to the antenna switch, wherein the first antenna feeding point 4 is disposed near the left edge of the antenna 1, the grounding point 3 is disposed on the right side of the antenna 1 far from the first antenna feeding point 4, the second antenna feeding point 5 is disposed on the antenna 1 between the first antenna feeding point 4 and the grounding point 3, and the second antenna feeding point 5 is preferably disposed adjacent to the grounding point 3.
The antenna switch can be a single-pole double-throw switch, and the control mode can be GPIO interface control or MIPI interface (mobile industry processor interface) control of a processor of the mobile terminal. The control logic is that when the switch is switched to the first antenna feed point 4, the second antenna feed point 5 is equivalent to an open circuit, and radio frequency signals are transmitted from the first antenna feed point 4; when the switch is switched to the second antenna feed point 5, the first antenna feed point 4 acts as an open circuit and the radio frequency signal is transmitted from the second antenna feed point 5.
In the invention, the antenna 1 is rectangular, and two corners at the left side and the right side of the lower end of the antenna 1 are round corners.
As a preferred aspect of the present invention, the grounding point 3 is disposed at a position one third of the total length of the antenna 1, and more preferably, the distance from the grounding point 3 to the edge of the antenna adjacent to the grounding point 3 of the antenna 1 is about 4 mm; the distance from the first antenna feed point 4 to the edge of the antenna adjacent to the first antenna feed point 4 is about 5 mm; the distance between the first antenna feed point 4 and the second wire feed point 5 is about 45 mm.
The mobile device of the present invention includes a metal housing 6, and further includes the antenna with the switchable antenna feeding point on one side of the metal housing 6, and the structure of the antenna is the same as that of the antenna with the switchable antenna feeding point, which is not described herein again.
The mobile device in the invention can be a mobile device with an antenna, such as a mobile phone, a tablet and the like.
The operating principle of the invention is that when the switch of the first antenna feed point 4 is on and the switch of the second antenna feed point 5 is off, the antenna as a whole is a LOOP (LOOP) antenna. A low frequency resonance can be generated, and at the same time, a resonance can be generated at the medium frequency and the high frequency by second and third frequency doubling, and the metal part at the right corner of the grounding point 3 also generates a resonance at the high frequency. Meanwhile, the resonant frequency can be switched and adjusted through matching at the first antenna feed point 4; when the second antenna feeding point 5 is turned on and the switch of the first antenna feeding point 4 is turned off, an IFA antenna is formed, a resonance can be formed at a low frequency, and the switching and adjustment of the resonance frequency can be performed by matching at the second antenna feeding point 5.
In the actual use process, the user scenes may be various, such as left-hand holding, right-hand holding and the like, when the low-frequency signal reaches the preset critical value of the mobile phone, the mobile phone automatically switches the feed point, compares the signal intensity in the two states and selects a stronger signal.
While the invention has been shown and described with reference to certain embodiments, those skilled in the art will understand that: various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
