Problems solved by technology

[0004] UWB antennas in the prior art include biconical antennas, disc-conical antennas and spherical antennas, etc., all of which are three-dimensional structures with huge volumes and are inconvenient to use. At the same time, they are also inconvenient to manufacture, and the actual use effect is poor.

Embodiment 1

[0032] The present invention provides such as Figure 1-5 The shown flame-shaped ultra-wideband planar monopole antenna includes a radiation stub assembly 1, and the radiation stub assembly 1 includes a first radiation stub 2, a second radiation stub 3 and a third radiation stub 4, and the radiation stub assembly 1 The component 1 is arranged in a spiral shape, and the radiating stub component 1 is connected with a tapered microstrip feeder 5 , the bottom of the radiating stub component 1 and the tapered microstrip feeder 5 are fixed with a dielectric substrate 6 , and the bottom of the dielectric substrate 6 is fixed with a There is a grounded metal plate 7.

[0033] It can be known from the above-mentioned embodiments that the present invention provides the radiation stub assembly 1, the tapered microstrip feeder 5, the dielectric substrate 6 and the ground metal plate 7, and at the same time the radiation stub assembly 1, the tapered microstrip feeder 5, the dielectric subs...

Embodiment 2

[0044] The difference with embodiment 1 is: by Figure 6 It can be seen that the helical shape specifically includes a lollipop shape, thereby reducing the production difficulty of the radiation stub assembly 1 while slightly reducing the performance of the radiation stub assembly 1 , making the present invention more suitable for industrial production.

[0045] The working principle of the present invention:

[0046] Refer to the attached figure 1 , attached figure 2 And attached Figure 4 , the present invention is provided with a radiation stub assembly 1, a tapered microstrip feeder 5, a dielectric substrate 6, and a ground metal plate 7, and simultaneously adopts a planar structure to the radiation stub assembly 1, a tapered microstrip feeder 5, a dielectric substrate 6, and a ground metal plate 7 Arrangement is carried out so that the production and processing of the present invention can be carried out by PCB processing technology during actual manufacturing. The fi...

Abstract

The invention discloses a flame-shaped ultra-wideband planar monopole antenna, and in particular relates to the field of antennas. The flame-shaped ultra-wideband planar monopole antenna comprises a radiation branch assembly; the radiation branch assembly comprises a first radiation branch, a second radiation branch and a third radiation branch; the radiation branch assembly is set to a spiral structure; a gradient micro-strip feeder is connected onto the radiation branch assembly; a dielectric substrate is fixedly arranged at the bottoms of the radiation branch assembly and the gradient micro-strip feeder; and a grounded metal plate is fixedly arranged at the bottom of the dielectric substrate. When being actually manufactured, the flame-shaped ultra-wideband planar monopole antenna in the invention can be produced and processed through a PCB processing technology; a produced product is relatively simple in structure, relatively small in volume and low in manufacturing cost; simultaneously, the product is easily integrated with other circuits; the space utilization rate is increased; use is relatively convenient; and the actual use effect is better.

Description

technical field [0001] The invention relates to the technical field of antennas, and more specifically, the invention relates to a flame-shaped ultra-wideband planar monopole antenna. Background technique [0002] In recent years, with the increasing demand for positioning services, wireless positioning technology has achieved unprecedented development. The current popular wireless positioning technologies mainly include: infrared positioning, ultrasonic positioning, base station positioning, radio frequency identification positioning, assisted global positioning technology and ultra-wideband wireless positioning, etc. Compared with other positioning systems, ultra-wideband positioning system has unparalleled Advantages, it uses narrow pulse transmission signal, the instantaneous power of the signal is very strong, so the penetrating ability and anti-interference ability are strong; and in the frequency domain, the narrow pulse signal occupies a wide spectrum, which means th...
