Abstract

The invention provides a three-channel integrated short-wave receiving antenna, belonging to the field of receiving short-wave frequency band signals and comprising a whip antenna, a first loop antenna, a second loop antenna, an upper cavity, a lower cavity, a base and an earth screen, wherein the whip antenna is internally provided with a whip antenna core which is welded with a connecting metal base at the lower part; the connecting metal base is in threaded connection with a socket core and connected with an input end of a whip antenna amplifier through the lower cavity; an output end of the whip antenna amplifier is connected with an RF (radio frequency) connector by a guide line; the first loop antenna is internally provided with a loop antenna core which is connected to an input end of a first loop antenna amplifier by an outgoing line; the second loop antenna is internally provided with a loop antenna core which is connected with an input end of the second loop antenna amplifier by an outgoing line; and the second loop antenna is fixed with the first loop antenna crosswise by the upper cavity and the lower cavity. The three-channel integrated short-wave receiving antenna is suitable for vehicle-mounted and portable equipment and reaches preferable receptivity and channel number in the smaller space.

Description

technical field

[0001] The invention belongs to the field of receiving short-wave frequency band signals, and in particular relates to a miniaturized three-channel integrated short-wave radar receiving antenna technology. Background technique

[0002] Ordinary short-wave antennas are large in size, and the antenna array occupies a huge area. For vehicle-mounted and portable devices, small antenna size is the most basic requirement. At present, there are some relatively mature technologies for short-wave small receiving antennas, such as helical antennas and small loop antennas.

[0003] For example, the utility model patent with the notification number CN201126858 discloses a relatively small-volume broadband high-gain high-power omnidirectional shortwave antenna. The antenna mainly consists of three parallel bottom-fed whip antennas 2, 3, 4 with a total height H located on a circle with a radius R. At the feeding point, a small whip antenna 15 with a height of H↓[2] is ad...
