Dielectric-loaded miniaturized ultra-wideband antenna structure and electronic equipment

Abstract

The invention discloses a dielectric-loaded miniaturized ultra-wideband antenna structure and electronic equipment, and the structure comprises a PCB and a shielding case, the shielding case is disposed on the PCB, a slot antenna is formed on the surface of the shielding case, the slot antenna comprises a slot, and a dielectric material is loaded in the slot. The ultra-wideband antenna is designedand realized on the shielding cover, so that an antenna does not need to be additionally configured, and the sizes of an ultra-wideband system and a module can be effectively reduced; the antenna isin the form of the slot antenna, and the metal ground reflection characteristic of the ultra-wideband module PCB is utilized, so that the antenna forms a directional radiation characteristic, and thepart, facing a human body, of radiation energy can be effectively reduced; according to the slot antenna, the dielectric material is loaded in the slot antenna, the physical size of the slot antenna during working can be reduced by utilizing the effect that the wavelength of electromagnetic waves in a medium is shortened, and correspondingly, the antenna radiation performance of the same frequencyband can be realized on a smaller shielding cover, so that the sizes of an ultra-wideband system and an ultra-wideband module are further reduced.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a medium-loaded miniaturized ultra-wideband antenna structure and electronic equipment. Background technique [0002] Ultra-wideband (UWB) utilizes pulse radio communication technology to realize information interaction in a wide frequency range, and its typical function is to obtain location information, that is, precise positioning. In the field of consumer electronics, the wide application of ultra-wideband technology depends not only on the universal integration of ultra-wideband circuit modules in smartphones, but also on the rich ultra-wideband ecological products, including various label devices, so as to effectively serve the daily life of ordinary consumers. Life. All these products are eager for smaller product form, and the antenna, as an indispensable key component, must also develop towards miniaturization. [0003] Such as figure 1 as shown, figure 1 It is a sc...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 as shown, figure 1 It is a schematic diagram of a typical ultra-wideband circuit module, showing the three necessary components of the circuit module: shielding cover 200, PCB board 100 and antenna 300, wherein the antenna is realized by a metal pattern printed on the surface of the PCB, which is the current circuit Common antenna implementation in the module, which requires additional PCB area, making the overall module size larger

[0004] in addition, figure 1 Most of the antennas used have omnidirectional radiation characteristics, the advantage is that they can cover a wider area, but the potential disadvantage is the impact on the human body

It can be seen that a large part of the radiated energy is directed towards human hands, which is bound to have potential adverse effects on human health.
