Shapes and Boolean Operations

Geometric shapes, mathematical operations

Use the geometrical shapes and mathematical operations to create and combine unique antenna geometries suitable for your antenna specifications. For example, you can use these objects and functions in pcbStack, to create single or multi-layered PCB-based antenna designs.

Objects

`antenna.Circle`	Create circle centered at origin on X-Y plane
`antenna.Polygon`	Create polygon on X-Y plane
`antenna.Rectangle`	Create rectangle centered at origin on X-Y plane

Functions

`add`	Boolean unite operation on two shapes
`area`	Calculate area of shape in sq.m
`subtract`	Boolean subtraction operation on two shapes
`intersect`	Boolean intersection operation on two shapes
`plus`	Shape1 + Shape2
`minus`	Shape1 - Shape2
`and`	Shape1 & Shape2
`rotate`	Rotate shape about axis and angle
`rotateX`	Rotate shape about X-axis and angle
`rotateY`	Rotate shape about Y-axis and angle
`rotateZ`	Rotate shape about Z-axis and angle
`translate`	Move shape to new location
`show`	Display antenna or array structure; Display shape as filled patch
`mesh`	Mesh properties of metal or dielectric antenna or array structure
`plot`	Plot boundary of shape
`scale`	Change the size of the shape by a fixed amount

Modeling and Analysis of Single Layer Multi-band U-Slot Patch Antenna

The standard rectangular microstrip patch is a narrowband antenna and provides 6-8 dBi Gain with linear polarization. This example based on the work done in [1],[2], models a broadband patch antenna using a slot in the radiator and develops a dual-band and a tri-band variation from it. In the process, the single wide response has been split into multiple narrow band regions catering to specific bands in the WiMAX standard. These patch antennas have been probe-fed.

Design an Internally Matched Ultra-wideband Vivaldi Antenna

Will model and analyze a vivaldi antenna with an internal matching circuit. The vivaldi is also known as an exponentially tapered slot antenna. The antenna possesses wideband characteristics, low cross polarization and a highly directive pattern. The design will be implemented on a single layer dielectric substrate with 2 layers of metal; one for a flared slot line, and the feed line with the matching circuit on the other layer. The substrate is chosen as a low cost FR4 material of thickness 0.8 mm. The design is intended for operation over the frequency band 3.1 - 10.6 GHz [1].
