I need a complete electromagnetic design package for a Ku-band monopulse antenna that operates reliably across 12-18 GHz. The antenna will be the heart of a precision tracking system, so both the sum (Σ) and difference (Δ) patterns must be tightly controlled with excellent boresight stability and low side-lobe levels. Please base the work on industry-standard simulation tools such as CST, HFSS, or FEKO and keep the feed network fully compatible with standard WR-62 waveguide interfaces. I am happy to discuss options on aperture technology—horn array, reflectarray, or planar—but whichever architecture you select must meet the tracking accuracy targets we set together. Deliverables I need at the end: • 3-D CAD model and native simulation files • Radiation patterns (Σ and Δ) showing gain, side-lobe, and null depth across the whole 12-18 GHz span • Detailed feed network layout with amplitude / phase balance data • Brief manufacturing notes and recommended materials so the design can move straight into prototyping I will verify the work by replicating your simulation results and checking that the Δ null stays within ±0.1 ° of boresight while maintaining at least 25 dB isolation between Σ and Δ ports. If you have already produced similar Ku-band tracking antennas, a quick note on past results will speed up the decision.

Hi I will design a high-precision Ku-band (12–18 GHz) monopulse antenna with tightly controlled Σ and Δ patterns, ensuring excellent boresight stability, low side-lobes, and ≥25 dB isolation using CST/HFSS. The feed network will be fully WR-62 compatible, with optimized amplitude and phase balance to meet ±0.1 degree null accuracy. I have previously designed similar tracking and Ku-band antenna systems. As a Top-Rated freelancer with 300+ completed engineering projects, I deliver simulation-verified designs with complete documentation.

Hi, I am an Electronics Engineer with strong experience in RF and electromagnetic design, and I can deliver a complete Ku-band (12–18 GHz) monopulse antenna package optimized for precision tracking applications. Using CST or HFSS, I will design and validate a Σ/Δ architecture (horn array, reflectarray, or planar—selected based on performance trade-offs) that meets tight boresight stability (Δ null within ±0.1°) and ≥25 dB Σ/Δ isolation requirements, fully compatible with WR-62 waveguide interfaces. Deliverables will include native 3D EM models, broadband radiation patterns (gain, SLL, null depth), a balanced monopulse feed/comparator network with amplitude and phase tracking data, and manufacturing notes with material recommendations. The design will be simulation-verified across the full 12–18 GHz span and prepared for direct prototyping.

Hi Client, I have strong experience in antenna design and simulation using CST Studio and ANSYS HFSS. Recently, I successfully designed a complex 2x2 and 4x4 array antenna (on CST) and also dual-band patch antenna resonating at 19 GHz and 38 GHz (on HFSS) and I designed a 1 to 4 Wilkinson power divider using ADS with fabrication. I'm ready to start immediately lets chat and discuss more the details

Hi. I'll be completely honest with you: getting a ±0.1° null stability and 25 dB isolation across a 40% fractional bandwidth (12-18 GHz) is a brutal hardware challenge. The monopulse comparator network is going to be incredibly sensitive to phase and amplitude imbalances over that wide of a sweep. I'm an RF engineer heavily focused on full-wave EM solvers (mostly Ansys HFSS). I haven't deployed a Ku-band monopulse for a precision tracking system yet, but I spend my days designing complex feed networks, phase shifters, and corporate combiners for phased array systems, as well as wideband CP antennas. I know how to grind through parametric sweeps until the feed is perfectly balanced. Given the WR-62 waveguide requirement, a waveguide slot array or an SIW planar design is probably the smartest route here. My plan is to focus entirely on optimizing the feed network (the magic tee/hybrid) in HFSS first to lock in that 25 dB isolation, before even touching the radiating aperture or SLLs. I'm bidding the absolute minimum because I want a Ku-band tracking project of this caliber in my portfolio. I will put in the simulation hours that the older guys won't. Do you have a strict preference for the aperture type yet (planar vs horn array), or do you want me to run a quick trade-off analysis to start?
