Port Analysis of Antenna
Quantifies terminal antenna parameters, with regard to the antenna port. The antenna is a one-port network. The antenna port is a physical location on the antenna where an RF source is connected to it. The terminal port parameters supported in Antenna Toolbox™ are
Antenna Array Analysis
Create and analyze antenna arrays in Antenna Toolbox™, with emphasis on concepts such as beam scanning, sidelobe level, mutual coupling, element patterns, and grating lobes. The analyses is performed on a 9-element linear array of half-wavelength dipoles.
Plane Wave Excitation - Scattering Solution
Explains how to excite an antenna using a plane wave. The antenna in this case can be thought of as a receiving antenna. A receiving antenna may be viewed as any metal object that scatters an incident electromagnetic field. As a result of scattering an electric current appears on the antenna's surface. The current in turn creates a corresponding electric field. This produces a voltage difference across the feed. This voltage constitutes the received signal. [1]
Direction of Arrival Determination Using Full-Wave Electromagnetic Analysis
This example shows how to determine the Direction of Arrival (DoA) when the transmission source is an antenna located in the far-field region or by assuming that the incident signal behaves like a plane wave incident on the receive array. DoA can be denoted by two angles phi and theta in the spherical co-ordinate system. It is a common practice to use a receive antenna array to scan for any incoming signals and to calculate its angles of arrival with respect to the center of the array. The incoming signal is commonly assumed to arrive from a far-field transmission source. Proper accounting of receive array’s electromagnetic behavior is one of the key elements in determining the angles of arrival of the incident signal.
