Internet of Things (IoT) devices
PW Series antennas are rugged, low-cost and
easy to install. The single frequency band of PW
antennas makes the job of antenna selection
simple, with better performance in the target
frequency band than in multiband antennas and
rejection of signals from unwanted frequencies.
The PW 410 antenna targets 410 MHz to 430 MHz
with excellent VSWR, gain and efficiency for 5G NR
bands 87 and 88.
This rugged 1/4-wave monopole antenna may be
used with plastic or metal enclosures and supports
weather-resistant applications.

VSWR
Figure 1 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.

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.

Counterpoise
Quarter-wave or monopole antennas require an associated ground plane counterpoise for proper operation.
The size and location of the ground plane relative to the antenna will affect the overall performance of the
antenna in the final design. When used in conjunction with a ground plane smaller than that used to tune the
antenna, the center frequency typically will shift higher in frequency and the bandwidth will decrease. The
proximity of other circuit elements and packaging near the antenna will also affect the final performance.
For further discussion and guidance on the importance of the ground plane counterpoise, please refer to Linx

Antenna Mounting
The antenna is attached by placing its cable and base through a 6.35 mm (0.25 in) hole in the product
enclosure and securing it with the included nut or by threading it into a PEM-style insert (not included).
The straight-cut RG-174 coax cable option allows the attachment of a 50-ohm RF connector or allows
the cable to be soldered directly to a PCB, eliminating the need for a connector. The connectorized
option provides a 1.32 mm coax cable terminated with a U.FL/MHF compatible connector for simplified
manufacturing or for applications requiring the ability to disconnect the antenna.

Figure 8. Radiation Patterns for PW 410 MHz Antenna
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 8), 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.

Antenna Definitions and Useful Formulas
VSWR - Voltage Standing Wave Ratio. VSWR is a unitless ratio that describes the power reflected from the
antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency.

measured in watts (W).

decibel (dB) - A logarithmic unit of measure of the power of an electrical signal.
decibel isotropic (dBi) - A comparative measure in decibels between an antenna under test and an isotropic
radiator.
decibel relative to a dipole (dBd) - A comparative measure in decibels between an antenna under test and
an ideal half-wave dipole.
Dipole - An ideal dipole comprises a straight electrical conductor measuring 1/2 wavelength from end to end
connected at the center to a feed point for the radio.
Isotropic Radiator - A theoretical antenna which radiates energy equally in all directions as a perfect sphere.
Omnidirectional - Term describing an antenna radiation pattern that is uniform in all directions. An
isotropic antenna is the theoretical perfect omnidirectional antenna. An ideal dipole antenna has a donut-
shaped radiation pattern and other practical antenna implementations will have less perfect but generally
omnidirectional radiation patterns which are typically plotted on three axes.
