SPE-23-8-012-A
The PCS.55.A, is a patent pending compact cellular antenna designed specifically for IoT devices with small ground planes. It combines revolutionary antenna design techniques with the antenna integration experience of Taoglas to provide a solution for wideband coverage of both 5G/4G LTE and GNSS bands, including the most challenging 600700MHz bands.
The PCS.55.A provides a simple off-the-shelf solution for LTE, LTE CAT-M, NB-IoT, & GNSS applications. At only 27x10x1.6mm, this compact cellular antenna is the perfect antenna for small IoT devices, where requirements for smaller PCB design are becoming more dependent on the antenna size. This antenna also has a relatively small keep-out area compared to most other compact cellular antennas that are on the market, owing to Taoglas' years of antenna design expertise.
Typical Applications include: - Handheld IoT Devices - Handsets and Tablets - Compact Asset Trackers
The PCS.55.A is available in three matching configurations. The optimum components for North America (NA), European Union (EU), and World Wide (WW) have been determined to allow designers to easily integrate the PCS.55.A to get the best performance for any particular deployment scenario. The PCS.55.A is easy to integrate using standard SMD technologies and the matching circuits for each deployment (NA, EMEA, or WW) have been simplified to a 3 component configuration to allow for greater flexibility on the user side.
Many antennas advertise a small form factor but with the hidden cost of implementing a large PCB ground plane. At Taoglas, we believe that the whole antenna system (antenna + ground plane) needs to be small to meet the evolving demands of the IoT market. As a result, we have performed experimental ground plane studies in order to be fully transparent on the effect of small ground planes on antenna performance. This allows our customers to have full visibility on how our antennas will perform on various different ground plane sizes. The data for these studies is shown in the Application Note on page 59. For further information or, integration and matching guidelines contact your regional Taoglas customer support team.

## Antenna Integration
For any given PCB size, the antenna should ideally be placed on the PCB’s shortest side, to take advantage of the ground plane. Optimized matching components can be placed as shown.
## PCB Layout - NA
The footprint and clearance on the PCB must meet the layout drawing in section (7.12). Note the placement of the optimized components. L1 is placed as close as possible to the RF feed (pad 1) within the copper keep out area. C1 is then placed tightly in series with C2 placed in parallel after that.

## PCB Layout - EMEA
The footprint and clearance on the PCB must meet the layout drawing in section (7.12). Note the placement of the optimized components. C1 is placed as close as possible to the RF feed (pad 1) across the copper keep out area. L1 is then placed tightly in parallel with C2 placed in series after that.
## PCB Layout - WW
The footprint and clearance on the PCB must meet the layout drawing in section (7.12). Note the placement of the optimized components. L1 is placed as close as possible to the RF feed (pad 1) within the copper keep out area. C1 is then placed tightly in series with L2 placed in parallel after that.

Matching components with the PCS.55.A are recommended for the antenna to have optimal performance on the evaluation board, located in the spaces specified in the above images. Additional matching components may be necessary for your device, so we recommend incorporating extra component footprints, forming a “pi” network, between the cellular module and the edge of the ground plane.

SPE-23-8-012-A
The effect of shortening the ground plane on antenna performance was evaluated. Using the evaluation board of the PCS.55.A, the PCB was cut back 10mm at a time and tested in an anechoic chamber. The results for North America (NA), Europe, Middle East, Africa (EMEA), and Worldwide (WW) are shown here:

## **8.10** Effects of Right Side PCB Ground on Antenna Performance |
The PCS.55.A antenna was tuned for a 120x80mm ground plane and the distance between the PCB ground on the right side of the antenna was parameterized and swept from 0 to 50 mm. The minimum condition, or 0mm, has the ground right up against the antenna and the maximum condition, or 50mm, has no ground on the right side of the antenna (i.e. a full 80x16mm keep out area). This was done in order to determine the minimum distance that the ground can be placed next to the antenna without affecting performance. The configuration with 25mm is shown below.
For minimal (0.2 dB) performance impact, a clearance of 25mm is recommended. Return loss and efficiency 25, 35 and 50mm clearance are shown below:

## **8.11** Correlation of CST Blackbox Model to Measured Results
To evaluate the accuracy of the CST Blackbox Model available to all customers, the following comparisons of return loss and efficiency have been made:
Please note the following simulated results were run at 18 cells/wavelength and with a -80 dB accuracy criterion. The measured results are for the PCS.55.A evaluation board with the NA tuning in place.

## Repeatability Study
In order to verify the repeatability of the design, 20 production samples of the evaluation board for the PCS.55.A were tested in an anechoic chamber on the same day with standard SMA torque of 1 N ⋅ m

The PCS.55.A can be assembled by following the recommended soldering temperatures are as follows:
*Temperatures listed within a tolerance of +/- 10º C
The PCS.55.A is not limited to the number of passes through the reflow process. Smaller components are typically mounted on the first pass, however, we do advise mounting the PCS.55.A when placing larger components on the board during subsequent reflows.
