It must be made clear that "embedded"
and "COTS" almost conflict with each other... Off
the shelf implies that the implimentation should
be easy, while embedded implies integrated within
I work with ceramic and PCB antennas
all the time as an FAE. The datasheet for this and
other PCB antennas typically describe free-space
results. Not many recommendations are provided from
the manufacturers on placement - since a radiator
placed inside ANYTHING will behave differently with
respect to impedance and radiation patterns.
Puse Engineering offers a wide variety of antenna
products very similar to Toaglas and Antenova. IF
you need more information on an equivalent, to this
part number, go to the following website and request
further info on the W3501 antenna. This antenna
(not on the website) is a stand-alone radiator similar
to the Taoglas antenna.
If you have very low volume (available space
for the antenna), then look for the W3502 - which
takes advantage of the PCB that it is conencted
to (via IPEX / U.FL connector).
