Example Embodiment
[0036] Example 1:
[0037] like figure 1 A magnetic dipole antenna based on a semi-open substrate integrated waveguide resonator of this embodiment, Figure 4 It is an antenna array composed of magnetic dipole antennas based on semi-open substrate integrated waveguide resonators.
[0038] figure 1 A magnetic dipole antenna based on a semi-open substrate integrated waveguide resonant cavity includes an upper dielectric plate and a lower dielectric plate, wherein the material of the upper dielectric plate is Taconic TLY-5, the thickness is 1.52mm, and the upper dielectric plate is The upper surface and the lower surface are respectively provided with a first metal floor 3 and a second metal floor 4. The metalized via group 1 included in the upper dielectric plate constitutes a semi-open substrate integrated waveguide resonator. The hole period of group 1 is 0.75mm, the width of the semi-open substrate integrated waveguide resonant cavity formed is 6.4mm, the diameter of the m...
Example Embodiment
[0044] Example 2:
[0045] like Figure 7 and Figure 8 As shown, in order to make the antenna beam scan, on the basis of Embodiment 1, another phase-shifting feed network 7 realized by a microstrip power divider with equal amplitude and different phases is used, and each array unit will obtain equal amplitude and different phases. excitation signal. Figure 7 It is the position map of the metallized vias corresponding to the antenna array. The metallized vias group consistent with Embodiment 1 is used. The central axis of the open-chip integrated waveguide resonator is positioned upward to achieve good impedance matching performance. Figure 8 The phase-shifted feed network 7, which shows equal amplitude and different phase microstrip lines, is composed of three one-to-two microstrip equal power dividers to realize the function of one-to-four equal power division. It can adjust the phase delay by adjusting the length, which connects the microwave adapter and the feeding p...
