1. Introduction
The CA.69 Ceramic Chip antenna from 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. 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.
This antenna is delivered on tape and reel. Small low frequency antennas such as
CA.69 need to be carefully tuned and integrated into devices to perform optimally
given the narrow band tuning required, so contact your regional Taoglas sales office
for support on gerber review of your layout, advice on ground-plane layout and
transmission line design. Taoglas also recommends we test your final device prototype
with CA.69 on board and provide final matching values.
Taoglas has tested the CA.69 mounted in realistic conditions in metal or semi metal
meter housings with the latest high power modules from Telit and achieved read
ranges of more than one hundred metres.

3. Return Loss
*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.
