EM.Picasso Tutorial Lesson 1
Title:
Analyzing a Microstrip-Fed Patch Antenna
What you will learn:
This tutorial guides you through all necessary steps required to set up and perform a basic planar method of moments (PMOM) simulation and visualize and graph the simulation results. Specifically, you will use a wizard to build and analyze a simple microstrip-fed patch antenna on a conductor-backed dielectric substrate.
EM.Picasso Tutorial Lesson 2
Title:
Designing a Patch Antenna with a Recessed Feed
What you will learn:
In this tutorial you will create the parameterized geometry of a microstrip-fed patch antenna with a recessed feed using a wizard. You will learn how to perform frequency sweeps as well as parametric sweeps of various design variables.
EM.Picasso Tutorial Lesson 3
Title:
Analyzing a Planar Microstrip Band-Stop Filter
What you will learn:
In this tutorial you will model a two-port planar filter that is excited by two independent scattering wave ports. You will first use a wizard to create a basic twoport microstrip through line. Then, you will add additional microstrip segments to complete your filter construction.
EM.Picasso Tutorial Lesson 4
Title:
Designing a Circularly Polarized Probe-Fed Patch Antenna
What you will learn:
In this tutorial you will analyze a probe-fed patch antenna and will become familiar with embedded via sets and probe sources. You will also define new variables and learn about radiation characteristics such as axial ratio. You will run a parametric sweep of the probe feed location and examine the circular polarization of your patch antenna.
EM.Picasso Tutorial Lesson 5
Title:
Analyzing Patch Antenna Arrays
What you will learn:
A patch antenna array is typically made up of 𝑁𝑥 ×𝑁𝑦 individual patch antennas (radiating elements) arranged on a rectangular grid with a uniform spacing of 𝑆𝑥 and 𝑆𝑦 along the X and Y directions, respectively. You can model patch antenna arrays in a number of different ways:
- Analyze a single isolated patch antenna and use an array factor for radiation pattern calculation. But this method ignores all the inter-element coupling effects.
- Analyze an infinite periodic patch structure and use an array factor for radiation pattern calculation. This method accounts for the interelement coupling effects, but it cannot capture edge and corner effects.
- Construct a finite-sized 𝑁𝑥 ×𝑁𝑦 patch array on a finite-sized substrate. This is a full-wave treatment of the antenna array structure but it may prove computationally very expensive.
In this tutorial you will try out the second and third methods from the above list and model a finite-sized probe-fed patch array structure.
EM.Picasso Tutorial Lesson 6
Title:
Analyzing a Periodic Frequency Selective Surface
What you will learn:
In this tutorial you will learn how to define a plane wave source. You will use the plane wave source to illuminate a periodic planar structure and compute its reflection and transmission characteristics. You will also learn how to define field sensors to compute and visualize the electric and magnetic field distributions.
EM.Picasso Tutorial Lesson 7
Title:
Designing a Slot-Coupled Patch Antenna
What you will learn:
In this tutorial you will simulate multilayer planar structures that contain several metal and slot objects located on different trace planes. You will also learn how to set up a constrained parametric sweep that ties up different object parameters.
EM.Picasso Tutorial Lesson 8
Title:
Analyzing a CPW-Fed Folded Dipole Slot Antenna
What you will learn:
In this tutorial you will learn how to construct and simulate slot structures. You will define coupled ports to model coplanar waveguide (CPW) structures.
EM.Picasso Tutorial Lesson 9
Title:
Designing a Microstrip Wilkinson Power Divider
What you will learn:
In this tutorial you will build and simulate a three-port planar circuit. You will also learn how to define a lumped element on a strip object to represent a lumped resistor.
EM.Picasso Tutorial Lesson 10
Title:
Optimizing a Microstrip Patch Antenna Design
What you will learn:
In this tutorial you will revisit the rectangular patch antenna design with a recessed feed, which you explored earlier in Tutorial Lesson 2. This time, however, you will define a design objective and will use EM.Picasso’s optimization utility to optimize the values of designated design variables to achieve your goal.
