SPE-13-8-077/A/WY Page 1 of 16 SPECIFICATION Part No. : CA.69 Product Name : 169 MHz VHF Ceramic Chip Monopole Antenna Feature : 25.2mm *5.1mm * 0.8mm Efficiency 10~15% (on evaluation board) Peak Gain - approx -7 dBi (on evaluation board) Low profile Compact Size RoHS Compliant

SPE-13-8-077/A/WY Page 2 of 16 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.

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.
