Design Patch Antenna Using Ansoft Designer
Posted : adminOn 1/2/2018Design of Narrow Slotted Rectangular Microstrip Antenna. On Ansoft Designer v-2.2.0 software. Patch antenna was Ansoft designer V.
Both HFSS and Ansoft Designer can be regarded as accurate. Given identical models, both tools should provide identical results within the numerical precision of their respective computation engines. The challenge is in the care taken by the user to ensure that the models are indeed identical.
Nonetheless for planar circuits, Ansoft Designer will generally reach a solution much more quickly than HFSS. At the conclusion of design development using Designer, many users will verify using HFSS if they are fortunate enough to have both tools. Hi, If you want to design a simple structure you can trust Ansoft designer. If you structure is a complex array of patches and if the dimensions of the dielectric and the ground are important you use HFSS. Citrix Mac Ica Client For Windows. What you can do is to design first your antenna on Ansoft designer and then export the mask (dxf or iges) to HFSS in order to avoid drawing on HFSS. Another parameter is the metal thickness: indeed you have to know that the metal thickness is not well simulated on Ansoft designer, espacially if the frequency is high (over 40GHz).
In that case you have to confirm with HFSS.

An antenna is a device that transmits and/or receives electromagnetic waves. Most antennas are resonant devices, which operate efficiently over a relatively narrow frequency band. An antenna must be tuned to the same frequency band that the radio system to which it is connected operates in, otherwise reception and/or transmission will be impaired. • How does an antenna work? Antenna is one type of transducer that converts the electrical energy into the electro-magnetic energy in form of electromagnetic waves.
Antennas are required by any radio receiver or transmitter to couple its electrical connection to the electromagnetic field. • Microstrip Antenna Antenna Patch Dielectric substrate Ground plane What is Micro-strip Antenna? In its most basic form, a Microstrip 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). • Different Shapes of Micro-strip Patch Elements • Different Parameters of Microstrip Antenna L = Length of the Micro- strip Patch Element W = Width of the Micro- strip Patch Element t= Thickness of Patch h = Height of the Dielectric Substrate. • CALCULATION OF PARAMETERS The methodology used is based on the design specs of a particular rectangular microstrip patch antenna: Where, C = free space velocity of light = Dielectric constant of substrate For Calculation of Width: W = = For Calculation effective dielectric constant: = Where, h = thickness of antenna For Calculation of Actual Length: L = • Basic Principles of Operation The patch acts approximately as a resonant cavity (short circuit walls on top and bottom, open-circuit walls on the sides). In a cavity, only certain modes are allowed to exist, at different resonant frequencies. If the antenna is excited at a resonant frequency, a strong field is set up inside the cavity, and a strong current on the (bottom) surface of the patch. This produces significant radiation (a good antenna).
• Micro-strip Line Feed. A conducting strip is connected to the edge of the patch. The feed can be etched on the substrate. Capacitive Feeding In this type of feeding the feeding is done to small another patch instead of main radiating patch. Feed Techniques Micro-strip antenna can be feed by variety of methods. This methods can be classified into two categories-contacting and non-contacting.
The foremost popular feed techniques used are: • The Coaxial feed or probe feed is a very common technique used for feeding Microstrip patch antennas. The center conductor of the coaxial connecter is soldered to the patch. Coaxial Feeding • Advantages of Micro-strip Patch Antenna Light weight and low volume. Low profile planar configuration which can be easily made conformal to host surface. Low fabrication cost, hence can be manufactured in large quantities. Supports both, linear as well as circular polarization. Can be easily integrated with microwave integrated circuits (MICs).
