<P>PROBLEM TO BE SOLVED: To obtain a printed circuit board of reduced size. <P>SOLUTION: A printed circuit board (4) is provided for surface mounting of electrical and/or electronic components, in particular an SMD (surface mounted device) antenna having a ceramic substrate (1) and at least one resonant track structure (20; 30). Also, the antenna is provided for single and multiband applications, in particular in the high-frequency and microwave range. One end of the resonant track structure (20) of the antenna is connected to the ground metallization body (41). Thus, a relatively large bandwidth is achieved with small dimensions of the antenna, and smaller board design can be obtained. <P>COPYRIGHT: (C)2003,JPO |
