Ignition specializes in enabling effective mobile communications. Using Ignition technology, we design and manufacture optimized antennas to make your wireless devices more competitive. Our mission is to help our clients develop innovative products and accelerate their time to market through our expertise in antenna design, testing, and manufacturing.

Ignition products are protected by Ignition patents.
All information contained within this document is the property of Ignition and is subject to change without prior notice. Information is provided “as is” and without warranties. It is prohibited to copy or reproduce this information without prior approval. Ignition is an ISO 9001:2015 certified company. All our antennas are lead-free and RoHS compliant.

ANTENNA DESCRIPTION

The Slim Reach Xtend TM chip antenna is engineered specifically for wireless headsets using Bluetooth ® and other wireless standards operating at the ISM 2.4 GHz band. The Slim Reach Xtend TM antenna has been designed to resonate at 2.65 GHz in free space conditions. This has been done purposely because the human head and plastic housing produce a frequency downshift of 150-250 MHz in the resonance frequency of the antenna. Based on our research and development in this area, you are not forced to test multiple antennas with different resonant frequencies.

Material: The Slim Reach Xtend™ antenna is built on glass epoxy substrate.

ELECTRICAL PERFORMANCE 

3.1. EVALUATION BOARD
The Ignition configuration used in testing the Slim Reach Xtend™ chip antenna is displayed in Figure 1.

Figure 1 – EB_NN01-104. Slim Reach XtendTM Evaluation Board.

Tolerance: ±0.2mm
Material: The evaluation board is built on an FR4 substrate. Thickness is 1.0mm. Clearance Area: 20.0 mm x 6.0 mm (BFF)

3.2. MATCHING NETWORK 

The specs of an Ignition standard antenna are measured in their evaluation board, which is an ideal case. In a real design, components nearby the antenna, LCDs, batteries, covers, connectors, etc affect the antenna performance. This is the reason why it is highly recommended to place pads compatible with 0402 and 0603 SMD components for a PI matching network as close as possible to the antenna feeding point. Do it in the ground plane area, not in the clearance area. This is a degree of freedom to tune the antenna once the design is finished and takes into account all elements of the system (batteries, displays, covers, etc). Please notice that different devices with different ground planes and different components nearby the Slim Reach Xtend™ chip antenna may need a different matching network. To ensure optimal results, the use of high Q and tight tolerance components is highly recommended (Murata components). If you need assistance to design your matching network, please contact [email protected], or try our free-of-charge 1 NN Wireless Fast-Track design service, you will get your chip antenna design including a custom matching network for your device in 24h 1.

3.3. VSWR AND EFFICIENCY
VSWR (Voltage Standing Wave Ratio) and Total Efficiency versus Frequency (GHz).

Figure 2 – VSWR and Efficiency (%) vs. Frequency (GHz).
NOTE: the frequency performance is centered in between 2.4 GHz and 2.5 GHz in headset designs. The effect of the device casing and the human body is taken into account.

3.4 RADIATION PATTERNS (2.4 – 2.5 GHz), GAIN AND EFFICIENCY

MECHANICAL CHARACTERISTICS

4.1. DIMENSIONS AND TOLERANCES

The black circle located on the top side of the antenna indicates the feed pad.

The Slim Reach XtendTM chip antenna is compliant with the restriction of the use of hazardous substances (RoHS). The RoHS certificate can be downloaded from  www.ignion.io.

4.2. SPECIFICATIONS FOR THE INK

Next figure shows the correct colors of the antenna:
4.3. ANTENNA FOOTPRINT

This antenna footprint applies to the reference evaluation board described on page 6 of this User Manual. Feeding line dimensions over the clearance zone described in Figure 4 apply for a 1.0 mm thickness FR4 PCB.

Tolerance: ±0.2mm
Other PCB form factors and configurations may require a different feeding configuration, feeding line dimensions, and clearance areas. If you require support for the integration of the antenna in your design, please contact [email protected].

ASSEMBLY PROCESS

Figure 5 shows the back and front view of the Slim Reach Xtend TM chip antenna, and indicates the location of the feeding point and the mounting pads:
As a surface mount device (SMD), this antenna is compatible with industry-standard soldering processes. The basic assembly procedure for this antenna is as follows:

1. Apply a solder paste to the pads of the PCB. Place the antenna on the board.
2. Perform a reflow process according to the temperature profile detailed in Table 3, Figure 7 on page 13.
3. After soldering the antenna to the circuit board, perform a cleaning process to remove any residual flux. Ignition recommends conducting a visual inspection after the cleaning process to verify that all reflux has been removed. The drawing below shows the soldering details obtained after a correct assembly process:

NOTE(*): Solder paste thickness after the assembly process will depend on the thickness of the soldering stencil mask. A stencil thickness equal to or larger than 127 microns (5 mils) is required. The Slim Reach Xtend TM antenna should be assembled following either Sn-Pb or Pb-free assembly processes. According to the Standard IPC/JEDEC J-STD-020C, the temperature profile suggested is as follows:

Table 3 – Recommended soldering temperatures.
Next to graphic shows the temperature profile (grey zone) for the antenna assembly process in reflow ovens.

PACKAGING

The Slim Reach Xtend™ chip antenna is available in tape and reel packaging.
