Product Specification Indica A10381-PS-1.1
Indica 2.4 GHz Chip Antenna
Part No. A10381 gigaNOVA® Product Specification
1 Features
• Designed for 2.4 GHz applications: Bluetooth® (BT, BT EDR, BT LE), Wi-Fi®
(802.11a/b/g/n), ZigBee®, etc.
• Ceramic chip antenna
• Low profile design for use with no ground beneath the antenna
• High efficiency
• Light weight
• Intended for SMD mounting
• Supplied in tape on reel
2 Description
Indica is intended for use with all 2.4 GHz applications. The antenna uses a ground plane
in order to radiate efficiently, but this ground plane must not extend underneath the
antenna itself.
Copper tracks on the host PCB are required for the antenna to work properly. For correct
integration, it is important to follow very closely the footprint drawings, preferably importing
the electronic files (dxf or Gerber) into the PCB layout CAD.
3 Applications
• Mobile phones
• PDAs
• PNDs
• Headsets
• PMPs / MP3s
• Electronic Shelf Labels
• PC-Cards
• Medical devices
• Sensors
• Laptops

10 Electrical interface
10-1 Transmission lines
• All transmission lines should be designed to have a characteristic impedance of 50
Ω
• The length of the transmission lines should be kept to a minimum
• Any other parts of the RF system like transceivers, power amplifiers, etc, should also be
designed to have an impedance of 50
Ω
Once the material for the PCB has been chosen (PCB thickness and dielectric constant), a
coplanar transmission line can easily be designed using any of the commercial software
packages for transmission line design. For the chosen PCB thickness, copper thickness and
substrate dielectric constant, the program will calculate the appropriate transmission line width
and gaps on either side of the track so the characteristic impedance of the coplanar
transmission line is 50
Ω
.

10-2 Copper Track
The copper tracks etched on the PCB form an integral part of the antenna, and any deviation
from the advised layout shown below will result in a loss in the antenna performance. It is best
that the copper track layout is imported from CAD files which are available from Antenova M2M
on request. Please contact sales@antenova-m2m.com for further details.

10-3 Matching circuit
The antenna requires a matching circuit that must be optimized for each customer’s product.
The matching circuit will require up to three components (0402 size), and an additional tuning
element is also required (0402 size) the following pad layout should be designed into the
device so the correct circuit can be installed.
Note: The tuning element by default is a 0402 zero ohm resistor
In addition to the matching circuit, a separate DC blocking capacitor will also be required
between the radio and the antenna matching circuit.
Note: The component values for the matching circuit will vary depending on the size of
the PCB and surrounding components. The impedance of the antenna should be measured
before selecting suitable matching components. Antenova M2M offers this service on request.

10-4 Antenna placement
Antenova M2M strongly recommends placing the antenna near the edge of the board.
Maximum antenna performance is achieved by placing the antenna towards the middle of the
PCB, as shown in the diagram below. Other configurations are possible but recommend
contacting Antenova for advice on any other antenna placement options.
Ground plane edge
Ground plane edge
Additional electronic components near the antenna should be at a distance of at least 2 mm
away from the ground plane edges. The antenna should also be clear of ground from both the
top surface of the antenna and below the antenna.

11 Soldering
This antenna is suitable for lead free soldering.
The reflow profile should be adjusted to suit the device, oven and solder paste, while
observing the following conditions:
- The maximum temperature should not exceed 240 ºC
- However for lead free soldering, a maximum temperature of 255 ºC for no more than
20 seconds is permitted.
- The antenna should not be exposed to temperatures exceeding 120 ºC more than 3
times during the soldering process.
12 Hazardous material regulation conformance
The antenna has been tested to conform to RoHS requirements. A certificate of
conformance is available from Antenova M2M’s website.
13 Packaging
13-1 Optimal storage conditions for packaged reels
