[0051] The dielectric substrate 11 can be made of FR4 material with a dielectric constant...

Embodiment 2

[0068] This embodiment provides a design method for a dielectric-loaded silver-paste-free antenna, which can be applied to the dielectric-loaded silver-paste-free antenna in Embodiment 1. The design method can adjust the matching degree of the metal conduction strip 13 and the annular slot 121 by changing the length of the metal conduction strip 13; the operating frequency of the microstrip slot antenna 1 can be controlled by changing the size of the annular slot 121; The size and the angle between the metal conduction band 13 introduce perturbation, so that the slot antenna 1 produces two orthogonal modes corresponding to two radiation resonance points, and the phase difference of the two orthogonal modes is adjusted to a difference of 90°, Make the slot antenna 1 have circular polarization; the Q value of the microstrip slot antenna 1 can be changed by changing the shape, size and dielectric constant of the dielectric block 2, so as to balance the miniaturization and bandwidt...

Embodiment 3

[0071] see Figure 6 , The method for preparing a medium-loaded silver-paste-free antenna in this embodiment can prepare the medium-loaded silver-paste-free antennas of Examples 1 and 2.

[0072] The preparation method comprises the following steps:

[0073] providing a dielectric substrate 11;

[0074] Printing the metal patch 12 and the metal conduction strip 13 on the upper and lower opposite surfaces of the dielectric substrate 11, respectively;

[0075] An annular slit 121 and two pairs of rectangular slits 122 are etched in the center of the metal patch 12, wherein the annular slit 121 is coupled with the metal conduction band 13; For symmetrical arrangement, two pairs of rectangular slits 122 are also arranged symmetrically with the center of the annular slit 121; radiate outward;

[0076] The dielectric block 2 is directly placed on the center position of the surface of the dielectric substrate 11 with the metal patch 12, and directly processed and formed.

Abstract

The invention discloses a medium-loaded silver-paste-free antenna for navigation and positioning, and a design and preparation method of the medium-loaded silver-paste-free antenna. The dielectric-loaded silver-paste-free antenna comprises a microstrip slot antenna and a dielectric block. The microstrip slot antenna comprises a dielectric substrate, a metal patch and a metal conduction band, wherein the metal patch and the metal conduction band are printed on the upper surface and the lower surface opposite to each other of the dielectric substrate respectively. The metal patch is provided with an annular gap coupled with the metal conduction band and two pairs of rectangular gaps symmetrically arranged with the center of the annular gap as a symmetric point. The two rectangular gaps in each pair of rectangular gaps are symmetrically arranged with the center of the annular gap as the symmetry point, one end of each rectangular gap is communicated with the outer edge of the annular gap, and the other end of each rectangular gap radiates outwards. A wide passband of the antenna is excited to cover four working frequency bands for positioning of the navigation system, and the antenna is simple and light in structure and excellent in performance, has the characteristics of low profile, low cost, wide axial ratio, low return loss, wide absolute bandwidth, stable radiation pattern and the like, and is suitable for the positioning function of the satellite navigation system.
