Abstract

The invention discloses a flexible and wearable miniaturized printed ultra-wideband monopole antenna. The antenna includes a grounding plate, a dielectric substrate, a feed network and a radiating patch. The thickness of the dielectric substrate is 0.8 mm. The grounding plate is arranged on one side of the dielectric substrate. The other side of the dielectric substrate is provided with the feed network and the radiating patch. The radiating patch consists of a semicircular structure and an inverted trapezoidal structure. Widths of the grounding plate and the dielectric substrate are equal. The upper part of the grounding plate is provided with a rectangular slot. According to the antenna of the invention, an impedance bandwidth range is 2.7-12.3 GHz, a frequency multiplication bandwidth is 4.56:1, and working frequency bands of ultra-wideband communication systems are covered. The antenna is small in size, simple in a structure and easy to manufacture, is suitable for wireless communication systems and devices, is recently a hot spot of research of the electromagnetic field and the wearable device field, and has great development prospects.

Description

technical field [0001] The present invention relates to the technical field of antennas, and more specifically relates to a flexible wearable miniaturized printed ultra-wideband monopole antenna. Background technique [0002] With the development of mobile communication, wireless communication develops very rapidly, and related wireless communication technology, communication system, communication equipment, etc. have also become the focus of research. Body-centered network is an important part of mobile communication, which makes wearable devices more and more important, and the research value of flexible wearable antennas is also increasing. However, with the emergence of wireless avalanche-based applications, problems such as tight frequency band resources, low frequency band utilization, narrow operating bandwidth, and overlapping operating frequency bands of different devices or antennas cannot be ignored, all of which affect the reliability of the antenna. and availab...
