Receivers, Antennas, and Signals¶

Course Overview¶

• Institution: MIT
• Course code: 6.661
• Track: RF, Microwave, and Antennas
• Tier: B
• Role: Supplement
• Level: Not standardized by provider (use prerequisites)
• Last reviewed: 2026-07-28

MIT's Receivers, Antennas, and Signals supplements receiver and antenna study through an open draft and thirteen solved problem sets, with strong textual reference but no video or lab.

Why choose this course

Supplement course. Useful for specific topics and best paired with a more complete mainline resource.

Before you start

• Recommended foundation: Electromagnetic Fields and Waves
• Recommended foundation: Circuit Analysis
• Recommended foundation: Communication Systems

Verifiable learning outcomes

• Explain the core models in RF, Microwave, and Antennas, including their assumptions and limits
• Solve representative derivations and problems, checking units, limiting cases, or numerical results

Workload and pacing

6 weeks at 5 hours/week. This maintainer planning estimate is derived from course role and the density of public practice and labs; it is not a provider workload promise. Pilot two weeks while logging instruction, practice, lab, and review time, then adjust the remaining plan when actual effort differs by more than 25%.

Safety level

Standard study. No physical lab is recorded; follow ordinary electrical, ergonomic, data, and equipment-use precautions.

Course Resources¶

Software, hardware, and cost

Software

• Maintainer-suggested open-source/free verification path: openEMS, scikit-rf, GNU Octave or Python 3, and KiCad
• The resource inventory does not list public code coverage; the tools above are only a maintainer-suggested independent check, not a provider requirement

Hardware

• The resource inventory does not list public lab coverage; default to simulation and do not purchase a vector network analyzer, calibration kit, shielded interconnects, attenuators, and course-specified fixture/antenna in a compliant lab. If extending the course independently, first verify provider scope and reassess safety

Cost note

The current maintainer path assumes no dedicated hardware purchase and prefers open-source/free software; this is not a provider requirement. If the provider separately lists commercial software, components, equipment, or institutional access, costs vary by provider, region, and institution.

Public resource coverage

Resources and access

“Listed by official page” means the link was discovered on a successfully fetched official source on the verification date; it does not guarantee that every region or account can open the target directly. Access does not grant redistribution rights. Re-check the provider page, target link, and third-party notices before downloading, adapting, or publishing material.

Practice and Verification¶

Practice loop

Receivers, Antennas, and Signals · MIT 6.661: Passive RF Network and Antenna-Matching Simulation

This is a maintainer-suggested self-study project for Receivers, Antennas, and Signals · MIT 6.661, not an official course assignment. Design a passive matching network, transmission line, or antenna model for RF, Microwave, and Antennas and audit S-parameters, passivity or stability, and manufacturing tolerance.

Origin: Maintainer-suggested project

Deliverables

• A specification of band, port impedance, geometry or materials, matching, and regulatory boundary
• Circuit or full-wave models, mesh and port settings, and parameter-sweep sources
• Raw S-parameters, Smith-chart data, efficiency or gain or loss, and tolerance Monte Carlo results
• A report comparing analytic, circuit, and field solutions and explaining resonance drift and mismatch failure

Verification

• Meet the predeclared return-loss or insertion-loss target over the nominal band and pass a passivity check
• Cover the DC or low-frequency limit, center frequency, band edges, and material-parameter extremes
• Cross-check at least five frequency points against transmission-line or matching equations within 5%
• Inject ±10% geometry or permittivity variation and report resonance shift and worst mismatch

Reproducibility

• Commit geometry, circuit, mesh, sweep, and post-processing sources
• Pin solver, material models, ports, meshing rules, and convergence tolerances
• Preserve raw Touchstone or field data, solver logs, and the generated report

Safety boundary: Simulation only — Use passive RF or antenna simulation only; do not transmit or connect power amplifiers, microwave sources, or unknown antennas, and do not violate local spectrum rules.

Risks, gaps, and boundaries

An open draft and thirteen solved problem sets are strong references, but the course is old and has no video or laboratory.

Completion evidence

• Weekly learning log with time, questions, corrected errors, decisions, next steps, and links to that week's reproducible artifacts
• Theory dossier with explicit assumptions, notation, derivation, units, and boundary conditions, checked by at least one independent method
• Simulation package with model or netlist, inputs, solver and version, parameter-sweep script, benchmark comparison, expected results, and one rerun command
• Design-review package with requirements and constraints, trade-offs, editable sources, applicable ERC/DRC/timing/stability checks, exports, and a reproduction test
