Antenna Design & Array Beamforming
From compact embedded radiators to high-density phased arrays. We simulate true co-site electromagnetic interaction, chassis edge diffraction, and radome dielectric loading before committing to tooling.
Planar Monopoles & Vivaldi Notches
Ultra-wideband tapered slot antennas and compact ground-clearance radiators for IoT, pulse radar, and cellular bands with optimized group delay flatness.
Microstrip & Aperture Arrays
Active element pattern extraction, scan blindness mitigation, mutual coupling suppression (< -25 dB), and true-time-delay corporate feeds.
Dielectric Resonators & Horns
High-efficiency DRA elements, corrugated feed horns, and full 3D radome transmission loss calculation with aerodynamic boresight error minimization.
Passive Microwave Components
Passive structures determine front-end insertion loss, port match, and harmonic rejection. We optimize high-Q planar filtering, power distribution, and low-loss routing using full-wave electrodynamics.
Power Division & Combining
Wilkinson equal/unequal power splitters, resistive star splitters, 90° branch-line hybrids, 180° rat-race rings, and Lange couplers.
Signal Routing & Attenuation
Microstrip directional couplers, symmetric Pi/Tee pads, multi-bit digital step attenuators, ferrite circulators, and microstrip isolators.
Filtering & Selection
Stepped-impedance low-pass filters, interdigital bandpass filters, compact hairpin resonators, transmission line notch stubs, and junction diplexers.
Impedance Matching
Quarter-wave impedance transformers, broadband planar baluns, DC bias tees, RF DC block capacitors, and precision 50 Ω RF terminations.
Passive Microwave Component Directory
Review closed-form scattering matrices [S], analytical equations, substrate recommendations, and initiate HFSS / ADS simulation scopes.
Electromagnetic Simulation Solvers
Replacing physical cut-and-try with deterministic computational electrodynamics. We deliver turnkey contract modeling, multi-solver verification, and CAD synthesis across Ansys HFSS, CST Studio Suite, Siemens Simcenter FEKO, and Keysight PathWave ADS / RFPro.
Ansys HFSS & Maxwell
Industry gold standard for 3D full-wave volumetric FEM, packaging, and installed SBR+ radar.
Ansys HFSS delivers finite element frequency-domain electrodynamics with automated adaptive mesh refinement that terminates only when S-parameter convergence thresholds are strictly satisfied.
Ansys HFSS Contract Engineering Services
We build fully parameterized, production-ready .aedt workspaces with exposed variables, analytical equation drivers, and convergence-verified boundary setups.
How Nikola RF Selects the Right Solver for Your Hardware
We do not force complex planar circuits into slow 3D FEM meshes, nor do we run surface MoM on closed cavity resonators. We select the mathematically exact solver—or hybrid co-simulation—to minimize RAM, accelerate convergence, and guarantee sub-1% empirical correlation.
Publication-to-HFSS CAD Pipeline
Evaluating academic papers or patent disclosures usually stalls at CAD setup. We programmatically extract dimensional equations and coordinate matrices to deliver fully parameterized, variable-driven .aedt workspaces.
