The RCL Series is useful in products where additional
height above the product’s case is needed or a slightly
wider operational bandwidth is desired. The 2.45GHz
version has a center-fed 1/2-wave element with an
internal ground reference.

Antenna Test Fixture
The adjoining diagram shows the dimensions of the fixture on
which the stated pattern and gain measurements were made.
This does not mean that your product must conform to this size
or antenna orientation, although it should be recognized that the
gain, pattern, and performance may increase or decrease
accordingly. Antenna Factor recognizes that our antennas are
often used in compact applications with less than ideal ground
planes. In some cases, the reference jig is smaller than optimum,
particularly with lower-frequency antennas. This is, in part, to
more accurately reflect the performance of the antenna in typical
real-world applications.
