1. Introduction
The CA.69 Ceramic Chip antenna from
This antenna is delivered on tape
Taoglas has tested the CA.69 mounted in
Taoglas 169 MHz is specifically designed
for VHF 169MHz band applications.
It is a high efficiency miniature SMD
edge mounted antenna with small
footprint requirement.
and reel. Small low frequency antennas
such as CA.69 need to be carefully tuned
and integrated into devices to perform
This chip antenna uses the main PCB as its
ground plane, thereby increasing antenna
efficiency. It is tuned for different PCB
sizes by simply changing the value of
the matching circuit. CA.69 antenna
electrical properties are symmetrical
therefore the antenna can be soldered
to the board from either side.

your layout, advice on ground-plane layout

Taoglas also recommends we test your final
device prototype with CA.69 on board and
provide final matching values.

* The antenna tuning depends on different antenna ground plane application.
Taoglas provides CAD.A.69 and CAD.B.69 evaluation boards to show performance when antenna
is parallel mounted to the ground plane or when it is orthogonally mounted to the ground-plane.
