ANT-8/9-FPC-UFL-100

## **ANT-8/9-FPC-UFL-100 Flexible Embedded LPWA 868/915 MHz Antenna** 

The 8/9-FPC antenna is a flexible embedded multiband antenna designed for use in 868 MHz and 915 MHz frequency bands for low- power, wide-area (LPWA) applications such as LoRaWAN®, Sigfox® and WiFi HaLow™ as well as other ISM and remote control applications. The 8/9-FPC provides a ground plane independent dipole embedded antenna solution comparable in performance to an external antenna. The 8/9-FPC’s flexibility and adhesive backing makes it easy to mount in unique and custom enclosures, while enabling an environmentally sealed enclosure and protection from tampering or accidental antenna damage. 

Connection is made to the radio via a 100 mm long, 1.13 mm coaxial cable terminated in a U.FL- type plug (female socket).

## **ANTENNA MOUNTING** 

The ANT-8/9-FPC-UFL-100 is a flexible, adhesive backed antenna that allows it to be permanently installed onto non-metallic surfaces. The adhesive backing is 3M 300LSE™, which provides excellent adhesion to high and low surface energy plastics. 3M 300LSE™ adhesive is resistant to solvents, humidity and moisture, as well as heat up to 121 °C (250 °F) for short periods. 

The antenna should never be bent to the point of creating a crease or allowing the angle of the bend to fall below 90 degrees (i.e. become acute) as this will impair function and may cause permanent damage.

## **VSWR** 

Figure 2 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna.

## **PEAK GAIN** 

The peak gain across the antenna bandwidth is shown in Figure 4. Peak gain represents the maximum antenna input power concentration across 3-dimensional space, and therefore peak performance, at a given frequency, but does not consider any directionality in the gain pattern.

## **RADIATION EFFICIENCY** 

Radiation efficiency (Figure 6), shows the ratio of power delivered to the antenna relative to the power radiated at the antenna, expressed as a percentage, where a higher percentage indicates better performance at a given frequency.

## **RADIATION PATTERNS** 

Radiation patterns provide information about the directionality and 3-dimensional gain performance of the antenna by plotting gain at specific frequencies in three orthogonal planes. Antenna radiation patterns (Figure 7), are shown using polar plots covering 360 degrees. The antenna graphic above the plots provides reference to the plane of the column of plots below it. Note: when viewed with typical PDF viewing software, zooming into radiation patterns is possible to reveal fine detail.
