How do I design an antenna?
Antenna Design Overview
- That the antenna is resonant at the same frequency as the radio signal applied and.
- That the feedpoint of the antenna is matched to the impedance of the attached transmitter energy source. Tip Maximum energy transfer between source and load ( the antenna)
How can you design a patch antenna to be circularly polarized?
Conventional designs of single-feed micro strip antennas for circular polarization (CP) are usually achieved by truncating patch corners of a square patch, using nearly square or nearly circular patches, cutting a diagonal slot in the square or circular patches, protruding or inserting a pair of symmetric perturbation …
Which type of software is used to design an antenna?
HFSS, which is an acronym for high frequency structural simulator, is one of the most advanced 3D EM software that is commonly used in antenna design and for the design of complex RF electronic circuits.
What is CST software for antenna design?
CST Studio Suite® is a high-performance 3D EM analysis software package for designing, analyzing and optimizing electromagnetic (EM) components and systems. Electromagnetic field solvers for applications across the EM spectrum are contained within a single user interface in CST Studio Suite.
How do Vivaldi antennas work?
Vivaldi antennas can be made for linear polarized waves or – using two devices arranged in orthogonal direction – for transmitting / receiving both polarization orientations. If fed with 90-degree phase-shifted signals, orthogonal devices can transmit/receive circular-oriented electromagnetic waves.
What is polarization in patch antenna?
5.9. For example, some patch antennas are approximately half a wavelength on each side. The polarization can be either circular or linear depending on the design of the patch. In a patch antenna, most of the propagation is above the ground plane and can have high directional gain.
What is the normalized radiation pattern for a microstrip antenna?
Figure 2. Normalized Radiation Pattern for Microstrip (Patch) Antenna. The directivity of patch antennas is approximately 5-7 dB. The fields are linearly polarized, and in the horizontal direction when viewing the microstrip antenna as in Figure 1a (we’ll see why in the next section).
When was the first micro-strip antenna invented?
Invented by Bob Munson in 1972 (but earlier work by Dechamps goes back to1953). 8. Different Parameters of Micro-strip AntennaOL = Length of the Micro-strip Patch ElementOW = Width of the Micro-strip Patch ElementOt= Thickness of PatchOh = Height of the DielectricSubstrate.
What is a micro-strip patch antenna?
A Micro-strip patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side. Invented by Bob Munson in 1972 (but earlier work by Dechamps goes back to1953).
What is the fringing E-field direction of a microstrip antenna?
Note that the fringing fields near the surface of the patch antenna are both in the +y direction. Hence, the fringing E-fields on the edge of the microstrip antenna add up in phase and produce the radiation of the microstrip antenna.
