Embodiment Construction

[0012] The present invention will be described below in conjunction with the accompanying drawings and embodiments.

[0013] Before designing the antenna of the present invention, a simple multi-layer earlobe model is first constructed to construct a realistic simulation environment. Combined with the simple model of the earlobe structure, set the initial antenna size. Place the designed transmitting antenna and receiving antenna on the surface of the skin layer on both sides of the model, and properly debug through the simulation results to obtain a suitable antenna structure and size.

[0014] Such as figure 1 As shown, the antenna is a single-sided printed planar structure, printed on an FR-4 dielectric substrate with a dielectric constant of 4.4, and the overall size is 20mm×20mm×1.6mm. The double-layer structure of the antenna is a metal layer and a dielectric substrate layer respectively. A coplanar waveguide structure is adopted. The metal layer consists of two part...

Abstract

The invention relates to a small ultra-wideband antenna for detecting the blood sugar concentration of the earlobe, which is of a single-sided printed planar structure and printed on a 20mm*20mm*1.6mmsubstrate. The small ultra-wideband antenna adopts a coplanar waveguide structure, and a metal layer includes a feeding patch and a grounding plate. The small ultra-wideband antenna is characterizedin that the feeding patch adopts a zigzag structure, the main body is a metal strip folded into a square wave shape, and one side is connected to a feeder through a transverse metal strip; and the specific size of the feeding part is obtained though simulation. The small ultra-wideband antenna has stable working characteristics in an ultra-wideband working frequency band, and can effectively transmit and receive high-frequency signals.

Description

technical field [0001] The invention relates to a small ultra-wideband antenna. Background technique [0002] At present, the incidence of diabetes continues to increase, and many non-invasive and minimally invasive methods inevitably bring physical pain and mental stress to patients, and increase the risk of infection. People are eagerly hoping for the birth of an accurate and non-invasive method for detecting blood sugar. [0003] With the rapid development of modern wireless communication technology, signal frequency band resources tend to be tight. In order to meet the growing military and civilian needs, the working frequency band of various microwave devices is gradually widening to high frequency. Compared with narrowband technology, ultra-wideband (UWB) technology, which has many advantages such as low power consumption, high precision, high speed, low cost and high performance, has a better development space. [0004] With the rapid development of microwave wirele...
