Embodiment 1

[0050] like figure 1 As shown, the present embodiment provides a non-self-complementary broadband antenna, including a monopole antenna 1, a slot antenna 2, a metal ground 3 and a feeder 4, and the monopole antenna 1 is connected to the feeder 4; the feeder The device 4 is used to provide a radio frequency signal to the monopole antenna 1, and the monopole antenna 1 is used to radiate electrical waves to the outside world, and both the monopole antenna 1 and the slot antenna 2 are arranged on the metal ground 3; the slot antenna 2 is used for Radiates electrical waves to the outside world. The slot antenna 2 and the metal ground 3 form a double triangle half-slot antenna 2 . Both the monopole antenna 1 and the feeding device 4 are arranged on the metal ground 3 , the metal ground 3 is located between the monopole antenna 1 and the feeding device 4 , and the plane where the monopole antenna 1 is located is perpendicular to the plane where the metal ground 3 is located. The sl...

Embodiment 2

[0057] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the metal ground 3 includes a first metal ground 301 and a second metal ground 302 , and the slot antenna 2 is a slot antenna.

[0058] The second metal ground 302 is vertically set on the first metal ground 301 , the monopole antenna 1 and the slot antenna 2 are both set on the second metal ground 302 , and one end of the slot antenna 2 is abutted on the first metal ground 301 . One end of the monopole antenna 1 away from the feeding device 4 is connected to the metal ground 3 , and the bottom side of the monopole antenna 1 is connected to the metal ground 3 . The plane where the monopole antenna 1 is located is perpendicular to the plane where the second metal ground 302 is located.

Embodiment 3

[0060] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1 and Embodiment 2.

[0061] This embodiment provides a novel non-self-complementary broadband antenna, including a monopole antenna, a slot antenna, a metal ground, and a feeding device. The metal ground includes a first metal ground and a second metal ground.

[0062] The monopole antenna part is composed of two parts. The vibrator part is a monopole antenna with a triangular metal structure. The ground part is the second metal ground on the plane where the slot antenna is located, and is located above the first metal ground as a whole. The half-slot antenna part is composed of two parts. The slot antenna part is a slot antenna with a metal structure whose slot shape is a double triangle. The ground part is divided into a whole large enough first metal ground.

[0063] The RF signal can be fed only to the monopole antenna, or only to the slot antenna, or to both the m...

Abstract

The invention provides a non-self-complementary broadband antenna. The non-self-complementary broadband antenna comprises a monopole antenna, a slot antenna, a metal ground and a feed device, the monopole antenna is connected with the feed device; the feed device is used for providing a radio frequency signal for the monopole antenna, and the monopole antenna is used for radiating electrical measurement waves to the outside; the monopole antenna and the slot antenna are both arranged on the metal ground; the slot antenna is used for radiating electrical measurement waves to the outside. By means of the relation between the input impedance of the monopole antenna and the input impedance of the half-slot antenna, wide impedance bandwidth and gain bandwidth are achieved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a non-self-complementary broadband antenna, especially a novel non-self-complementary broadband antenna. Background technique [0002] Recent developments in next-generation communication systems have raised the demand for radio frequency systems with high communication rates and large communication capacities, and thus, research on wideband antennas has received extensive attention. The methods to realize broadband antenna mainly include non-frequency variable antenna, graded structure antenna, broadband resonant structure antenna, and loaded reactance element or matching network antenna. [0003] A self-complementary antenna is a frequency-invariant antenna, which is an antenna of any shape, consisting of half of an infinitely extending planar sheet conductor. Since the shape of its complementary structure is exactly the same, the antenna and its complementary structu...
