A collection of six applications. VSimEM is a 3D electromagnetic simulator and VSimMD is optimized for microwave. Macintosh OS X, Linux, and Windows.

MININEC Pro Antenna Analysis Software
Blackcat Systems has a version of NEC software for antenna analysis. Macintosh OS X and Windows.

AppCAD RF & Microwave tools from HP & Agilent
This package includes calculators for Transmission Lines, Transistor Bias Circuits, Cascade Noise Analysis, Transistor Design Data, and more. Although written for Windows, it is well behaved under Wine (Windows emulation) and runs will in CrossOver on the Macintosh without Windows.

RF Toolbox
A handy set of tools for electronic design, not just RF. Macintosh OS X and Windows.

MacTXLine calculates parameters for transmission lines. Macintosh OS X only.

Filter Designer for lumped element filters.
Design of Butterworth, Chebyshev or Bessel lumped element filters. Macintosh OS X only.

Smith Chart

Matchmaker – RF Impedance matching software
Series Capacitor, Series Inductor, Shunt Capacitor, Shunt Inductor, Transmission Line, Open Stub Transmission Line, Shorted Stub Transmission Line, Open Series Transmission Line, Shorted Series Transmission Line. Macintosh OSX and Windows.

Trace Analyzer / Impedance Calculator
Trace Editor will find the impedance of coupled microstrips, coupled striplines, a pair of coplanar traces, and multiple traces coupled through a slot. Many output formats. Macintosh OS X, UNIX, Linux, and Windows.

HSPICE Waveform Viewer Download
This HSPICE waveform viewer is useful for engineers running HSPICE simulations routinely. It can display the transient or AC simulation results easily and generate publication quality plots. Macintosh OS X, UNIX, Linux, and Windows.

S-Parameter Explorer
Version 1.0 is free. Scattering parameters, or S-parameters, are the most common network representation in RF/microwave engineering. As the digital circuits are operating in the giga-hertz realm, S-parameters become necessary in many areas of electrical engineering. This tool is an S-parameter plotter and viewer. The utility answers the needs of viewing, and common manipulations, of S-parameters. Macintosh OS X, UNIX, Linux, and Windows.

Arbitrary transmission line calculator. Finds the properties (Zo, capacitance per unit length, velocity factor, electric-field distribution, etc) of a transmission line or directional coupler. Unlike the well known analytical formulas printed in any book on transmission lines, atlc has great flexibility, as any cross section can be analyzed. Source, can be compiled for Macintosh OS X.

A wide range of applets on transmission lines, electromagnetic waves and antennas. Macintosh OS X, UNIX, Linux, and Windows.

Free and pay versions. A full multiphysics simulation package. AC/DC, RF, Wave Optics, MEMS, Plasma, and Semiconductor modules available. Macintosh OS X, UNIX, Linux, and Windows.
Macintosh requirements:

Free and Open Source. The emGine Environment(TM) is a full-wave 3D electromagnetic field simulation environment solving Maxwell’s equations in time-domain. It is used for the modeling of high-frequency electromagnetic field in microwave circuits, antennas, resonators, microwave filters, hollow waveguides. Macintosh OS X, UNIX, Linux, and Windows.
Macintosh application must be built from source.
