The DAC series miniature dielectric antenna element is for 2.4-GHz wireless LAN systems. The flat-type antenna provides:
- Vertical polarization reception
- Low profile (6-mm max)
- Omni-directional in azimuth
- Low-interference design
- Central feeding point terminal
- Wide bandwidth
- Light weight
A layer of conductive film on the wall of the substrate's though hole connects the radiation electrode on the substrate's top surface with the ground electrode on the bottom. A conductive pin abutting the electrode's 50V impedance matching point feeds the inner conductor of a coaxial cable, while the ground electrode connects to the outer coaxial-cable conductor.
