Description

Technical Field

[0001] The utility model relates to the technical field of communication equipment, in particular to an external antenna with a small area and communication equipment. Background Art

[0002] Antenna is a device that radiates high-frequency electromagnetic energy into space through metal conductors of various shapes. It transforms the guided waves propagating on the transmission line into electromagnetic waves propagating in unbounded media, or vice versa. It is a component used to transmit or receive electromagnetic waves in radio equipment. Engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to work.

[0003] However, for some sophisticated communication equipment, the structure is compact, the space environment is poor, and the layout and utilization position is extremely limited. Ordinary antenna structures cannot achieve long-distance effects. There are certain limitations in the electromagnetic field signal size, transmission direction and distance, which greatly affects the effect of signal transmission. In the case that existing products are designed towards miniaturization and the application environment is complex, there is not enough space to set up multiple antenna structures, resulting in the inability to meet some broadband bandwidth requirements. Utility Model Content

[0010] A second intermediate frequency radiator is arranged in a second direction of the feeding point;

[0011] A high-frequency radiator, connected to the feeding point and arranged in a first direction of the feeding point;

[0014] A second low-frequency radiator, wherein the second low-frequency radiator is connected to the first low-frequency radiator and is located in a first direction of the first low-frequency radiator.

[0015] Furthermore, the low-intermediate frequency coupling slot is opened between the second low-frequency radiator and the first intermediate frequency radiator; the second low-frequency radiator includes a branch arm extending from the first low-frequency radiator to the first direction; the second low-frequency radiator is used to generate secondary resonant frequency doubling.

[0016] Wherein, the high-frequency radiator includes an "n"-shaped arm.

[0017] On the other hand, the utility model also provides a communication device, including the small-area external antenna as described above.
