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 antenna is delivered on tape

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.

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.

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.

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.
