Problems solved by technology
[0004] Due to the above-mentioned two kinds of slot antennas with half-wavelength resonance and quarter-wavelength resonance, although the mobile communication device can work in a multi-band mode, the working mechanism of these two slot antennas is relatively simple. , it is not easy to implement a multi-frequency architecture, and it is also relatively limited in the application of mobile devices

Embodiment Construction
[0023] The technical content and detailed description of the present invention are hereby described as follows in conjunction with the drawings:
[0024] see image 3 and Figure 4 , is a schematic diagram of the structural decomposition and assembly of the multi-boundary slot antenna of the present invention. As shown in the figure: the multi-boundary slot antenna 10 of the present invention includes: a substrate 1, a first passive component 2, a second passive component 3, a third passive component 4 and a signal feed point 5 .
[0025] The substrate 1 has a metal surface 11 on its upper side, and a strip-shaped slot 12 with a width of about 4 mm is provided on the metal surface 11. The slot 12 divides the metal surface 11 into an upper metal surface 111. And the lower metal surface 112. In this drawing, the substrate 1 is a microwave substrate.
[0026] The first passive component 2 is located at one end of the slot 12 and electrically connected with the upper metal su...

The invention relates to an antenna, especially a slot antenna with multiple boundary conditions. A slot antenna with multiple boundary conditions includes: a substrate, a first passive component, a second passive component, a third passive component, a signal feed-in point and a signal feed-in wire. One side of the substrate has a metal surface, and a slot is opened on the metal surface; the first passive component, the second passive component and the third passive component are located on the slot and connected to the upper metal surface and the The lower metal surface is electrically connected; the signal feeding point is located on the upper metal surface and the lower metal surface on two sides of the slot hole. In the present invention, several passive components are electrically connected to the slot hole of the slot antenna. At different frequencies, the impedance value of the passive component will change with the frequency, so that the impedance matching and resonance mode of the antenna have higher freedom. The height allows the slot antenna to work in a multi-band working environment.
Description
technical field [0001] The invention relates to an antenna, especially a slot antenna with multiple boundary conditions. Background technique [0002] With the rapid development of wireless communication technology and information processing technology, mobile phones, personal digital assistants (personal digital assistant, PDA) and other portable wireless communication devices are emerging and entering thousands of households, so that consumers can enjoy high-quality With all the conveniences brought by technology, these portable wireless communication devices have become an indispensable part of the daily life of modern people. [0003] Traditional slot antennas can be roughly divided into two designs, figure 1 A metal surface 101 is formed on a substrate 100, and a slot 102 is opened on the metal surface 101. The two ends of the slot 102 form closed ends 102a, and a signal feed-in point 103 is located in the middle of the slot 102. , when sending and receiving signals, ...
