i am facing problem when feeding conformal antenna with coaxial feeding? can any one give me HFSS or CST design of conformal antenna with coaxial feeding?
1. First calculate the diameters of inner and outer conductors of coaxial cable so that its impedance would be 50 ohms taking into consideration the dielectric material in between.
2. Draw first the outer cylinder with its surface as outer conductor and its fill as your dielectric where you have to choose its material from library
3. subtract the diameter of inner conductor from the outer one.
4. draw another cylinder with same dimensions and orientation as the subtracted cylinder to replace it but this time it will be totally conductor
5. choose an excitation port as a circle the same size as the outer cylinder and place it on one cross sectional side of the cylinder
6. on the other side connect two conductor wires; first wire connecting inner cylinder to radiating patch of the antenna; the second wire will connect the outer surface with ground of antenna.
ich want to build ein Coaxcial-Cabel with connector in CST, my question is, that i get the ready-made connector or not, and i can build in cst self Coaxcial, but i need help building connector in CST
You can use Discrete Port in the Simulation section. Then Pick a Point in the Edge of the outer conductor, and finally, Pick another point in the Edge of the inner conductor.
I have attached a coaxial-fed antenna and how I excite it. Moreover, I have attached the resultant S parameters.
