TDK Balanced Antenna for Use in UWB Applications
TDK has developed a multilayer chip antenna with a patented balanced radiator structure. The
antenna’s unique structure allows it to maintain similar performance regardless of ground plane
size. Unlike monopole antennas, which are dependent on ground plane size, this antenna has
been designed for ease of integration in various applications without the worry of complex
board re-designs. It is ideal for use in CardBus, CompactFlash or USB designs.

Parameter
i
There is a significant difference in ground plane
size but almost no difference in VSWR results.
The antenna bandwidth is not detuned by
changing the ground plane size.
