It is also important that the ground clearance is respected through **all layers** of the PCB. It is recommended to implement a matching network to optimize the antenna impedance in your application. Detailed view of antenna pads and copper clearance: _Unit: mm_ ## **Transmission Line** The transmission line should be kept as short as possible and be designed to have a characteristic impedance of 50Ω. Abracon recommends using a Co-Planar Waveguide with Ground (CPWG), which dimensions can be derived by any trusted calculator, using the correct input for PCB materials and layer stack-up. 5101 Hidden Creek Ln Spicewood TX 78669 ABRACON IS Phone: 512-371-6159 | Fax: 512-351-8858 **REVISION I.R: 12-12-24** ISO9001-2015 For terms and conditions of sales, please visit: CERTIFIED www.abracon.com | | ## **2.4GHz Loop Chip Antenna** ## **AANI-CH-0131** Request Samples Check Inventory **3.2 x 1.6 x 1.2 mm RoHS/RoHS II Compliant MSL Level = 1** ## **Measurement Setup** The radiation measurements were all done in an anechoic chamber with the antenna implemented on its evaluation board (Abracon AANI-CH-0131-EVB) that has a PCB size of 40 x 19 mm: ## **Reflection Characteristics – Return Loss** 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 **REVISION I.R: 12-12-24** For terms and conditions of sales, please visit: www.abracon.com ABRACON IS ISO9001-2015 CERTIFIED ## **2.4GHz Loop Chip Antenna** **AANI-CH-0131** Request Samples Check Inventory **3.2 x 1.6 x 1.2 mm RoHS/RoHS II Compliant MSL Level = 1** ## **Radiation Characteristics – Total Efficiency (dB)** ## **Radiation Characteristics – Total Efficiency (%)** 5101 Hidden Creek Ln Spicewood TX 78669 ABRACON IS Phone: 512-371-6159 | Fax: 512-351-8858 **REVISION I.R: 12-12-24** ISO9001-2015 For terms and conditions of sales, please visit: CERTIFIED www.abracon.com ## **2.4GHz Loop Chip Antenna** ## **AANI-CH-0131** a Request Samples Check Inventory **3.2 x 1.6 x 1.2 mm RoHS/RoHS II Compliant MSL Level = 1** ## **Radiation Characteristics – Maximum Gain** ## **Radiation Characteristics – 3D Pattern @ 2450 MHz** _Unit: dBi_ 5101 Hidden Creek Ln Spicewood TX 78669 Phone: 512-371-6159 | Fax: 512-351-8858 For terms and conditions of sales, please visit: www.abracon.com ABRACON IS **REVISION I.R: 12-12-24** ISO9001-2015 CERTIFIED ~~[~~ **2.4GHz Loop Chip Antenna** ## **AANI-CH-0131** ee **Radiation Characteristics – 2D Pattern @ 2450 MHz** **3.2 x 1.6 x 1.2 mm** Request Samples Check Inventory **RoHS/RoHS II Compliant MSL Level = 1** **==> picture [184 x 514] intentionally omitted <==** **----- Start of picture text -----**

It has an arbitrary size of 40 x 19 mm and includes an SMA connector. The purpose is to give a reference design for an optimal antenna implementation. The evaluation board can also be used to test other implementations by cutting and soldering the PCB into any device. The evaluation board has a matching circuit implemented next to the antenna. This is aimed to enable optimization possibilities for the user. The component positions are sized for 0402 (1005 metric) SMD components. The antenna requires a matching circuit to fine-tune the resonant frequency and achieve optimal balance. The evaluation board is pre-tuned for optimal performance in the 2.4–2.5 GHz range using the components listed below (equivalents may be used): X1 = 0.7 pF (Murata GJM1555C1HR70WB01) X2 = 1.8 pF (Murata GJM1555C1H1R8WB01) X3 = Not mounted However, it is common that the resonant frequency will shift during implementation in an arbitrary device. Therefore, this matching may be changed with other values/components/brands for compensation of such effects. This is further described in the General Implementation Guidelines section below. 5101 Hidden Creek Ln Spicewood TX 78669 ABRACON IS Phone: 512-371-6159 | Fax: 512-351-8858 **REVISION I.R: 12-12-24** ISO9001-2015 For terms and conditions of sales, please visit: CERTIFIED www.abracon.com | ## **2.4GHz Loop Chip Antenna** **AANI-CH-0131** **3.2 x 1.6 x 1.2 mm** Request Samples Check Inventory **RoHS/RoHS II Compliant MSL Level = 1** ## **General Implementation Guidelines** The antenna can be positioned in different ways, although there are some positions which are more beneficial. The below illustration shows a typical PCB with examples on different antenna positions (the GND cutout is not visualized): - The optimal position is usually option 1. Options 2 and 3 are also possible. - The antenna must be placed along the PCB edge, i.e., it cannot be placed in the middle (see “N/A”). - Option 2 or 3 may be the best option for PCB’s much larger than the evaluation board. The rectangular copper cutout in the footprint must extend through all layers of the PCB stack-up, ensuring there is **no copper on any layer in this area** . Additionally, a robust via structure around the cutout and along the edge of the ground plane is highly recommended for optimal performance. It is important to note that plastic and metal parts in close proximity to antennas may significantly affect antenna tuning and performance. For instance, a plastic housing above the antenna often causes the resonant frequency to shift downward. Since such effects are challenging to predict without detailed design information, it is recommended to measure the antenna performance in the final device after implementation. To compensate for potential frequency shifts, implementing a matching network on the antenna feed is advisable. Another general consideration for surface-mounted antennas relates to PCB population. Electrical components placed near the antenna may impact its tuning and radiation performance. To mitigate this, components in the surrounding area should be positioned below a topographical slope. This slope should begin at the PCB level near the antenna's designated keep-out zone and gradually increase in height as distance from the antenna grows.
