2D Pattern Plots
2D patterns have a higher degree of precision or resolution vs 3D
patterns. Cuts usually come from the phi and theta planes which
correspond to the E and H planes. These types of plots are well suited
for directional antennas but can be used for any.
Antenna Efficiency Plots
Antenna efficiency plots are based on the integration of measured points
over a sphere for specific frequencies. Here we can calculate your
carrier minimum requirements and determine if the antenna design and
radio will meet those minimums.
3D Gain Plots
3D gain patterns have lower resolution than 2D patterns but offer a
visual representation over the entire sphere. These plots are better
suited for non-directional antennas to reveal null zones and
directionality.
Return Loss and S-Parameter Plots
Scattering parameters or S-Parameters plots are the bread and butter for
antenna design. During the design process vector network analyzers
(VNAs) are heavily used to determine power metrics and assist in the
iterative process. These types of measurements are usually the starting
point and precede efficiency and pattern plots.
Project Specific Reports:
Our reporting structure adapts alongside your project requirements. As specifications evolve, reports are updated to reflect mechanical constraints, physical or electrical modifications, comparison plots, and radiated performance metrics. Our cost-focused approach also allows you to select only the measurements and metrics needed to maintain project efficiency and momentum.
