What is full form of CST in antenna?
CST – Computer Simulation Technology. One Comment.
Which antenna is complementary to the slot antenna?
Antenna Elements and Arrays The complementary strip dipole is to be excited by a voltage gap, breaking across the strip at the same position where the slot antenna is excited. If the slot antenna is superimposed on its complementary dipole antenna structure, one would obtain an infinite conducting plane.
Which is better CST or HFSS?
CST is better than HFSS. Its time domain solver is fast and accurate. CST microwave studio is a fast and user friendly code for antenna designed.
Where is slot antenna used?
Slot antennas are usually used at UHF and microwave frequencies at which wavelengths are small enough that the plate and slot are conveniently small. At these frequencies, the radio waves are often conducted by a waveguide, and the antenna consists of slots in the waveguide; this is called a slotted waveguide antenna.
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.
Why slots are used in antenna?
Slots are mainly created to have new resonance frequency. When they are placed at the bottom layers, the gain of the antenna will increase. In more of the cases, if slots are done on the patch, the gain will decreases in cost of additional resonance due to the metallic diminution.
What is the difference between CST and HFSS?
HFSS is based on Finite Element Method (FEM) which is more accurate for designing antennas while CST is based upon Finite Integration in Technique (FIT) and is also popular among antenna designers due to ease in simulations. It can be used for planar antennas as well and is based upon MoM (Method of Moment).
What kind of antenna does CST Microwave Studio use?
Simulation MPA using CST MICROW AVE STUDIO “ PRINTED ANTENNAS ”. ◼ Operates on microwave frequencies ( f > 1GHz). ◼ Invented by Bob Munson in 1972. ◼ Metal “ Patch ”. ◼ Dielectric Substrate. ◼ Ground Plane. ◼ Easy to fabricate. ◼ Low cost , Less size.
How to design a microstrip patch antenna using CST?
ANTENNA USING LINE FEED The structure of this rectangular microstrip patch antenna is shown in Fig.2. In designing rectangular microstrip patch antenna using line feed, we use equation from Eq. 5 to Eq. 11 .
Which is correct for a narrow slot antenna?
A narrow slot approximation is used. This means that the E-fields in the slot are assumed to all be pointing in the x-direction and that the x-dependence of the electric fields in the slot is assumed to be uniform. The currents on the microstrip line were also assumed to be laterally uniform.
