| 摘要 |
A printed circuit board ( 4 ) is described for surface mounting of electrical and/or electronic components, in particular an SMD (surface mounted device) antenna with a ceramic substrate ( 1 ) and at least one resonant track structure ( 20; 30 ), and such an antenna for single and multiband applications, in particular in the high-frequency and microwave range. Since one end of the track structure ( 20 ) of the antenna is connected to the ground metallization ( 41 ), a relatively large bandwidth is achieved with small dimensions of the antenna plus the possibility of smaller board design.
