Hello every body, I'm student, i have to do a pifa antenna with coxiale Feeding. I have designed the antenna but i can't assign the materiel of the : shorting pin = Copper Ground = Copper and the material of the two cylindres of the coaxiale Cable. Can any one help me to configure the antenna using HFSS. The pifa (...)
Hello, my problem is as simple as it can be. I just wanna design a pifa shorting pin. I'm starting to study antennas, I'm really new at this. I'm aware of wavelength formula,if I got my L1 + L2 to be a quarter wavelength, I got it resonant to my frequency, is that right? I find it too easy and insanely small. f = 2,4Ghz -> (...)
Is no formula to find the impedance of pifa. There is a formula to get approximate resonant frequency having the dimensions of the planar element. Length + Width = λ/4 The impedance matching is obtained by positioning the feeding point and ground shorting pin on the planar element.
Why don't you use pifa? Your design is more or less close to pifa without the shorting pin. Anyway, in your simulation, the feeding was not correctly setup. I tried to change the feeding to get some results. However, it's not the best way to do it. Take a look at the attachement. you need to change the dimensions to get (...)
As with any antenna, increase the (electrical) volume. So you can increase the distance between groundplane and patch as well as the patch width. If you use a dielectric, decrease dielectric constant; air is of course best. Also the wdith of the shorting pin influence on the bandwidth. More advanced methods make use of slots in the patch, parasi
Respected sir, i am having doubt in the fabrication of pifa antenna. actually it contains both the ground plane and the radiating patch and the shorting pin connects the ground plane and the radiating patch and one coaxial probe feed is from the ground plane to the radiating patch. (...)
Respected sir, I am jayanthi doing M.Tech in NIT Trichy. I have designed pifa antenna and i am having doubt in the fabrication of pifa antenna. actually it contains both the ground plane and the radiating patch and the shorting pin connects the ground plane and the radiating patch and one (...)
Hi, jayanthi: I am not sure whether you need to use 2D DXF or 3D DXF. If it is 3D DXF, you can use the polygons from IE3D as they are. If you are using 2D DXF, you may try to build your shorting pin and probes as some shapes on a layer. You should have 3 layers: (1) patch layer; (2) ground layer (3) shorting pin and via (...)
Hi, Jayanthi: Please check the fabri.geo. The shorting pin is not electrically connected to the finite ground. By IE3D definition, you do need to have matching vertices to get guaranteed electrical connection. best regards, Added after 2 hours 53 minutes: Hi, jayanthi: I did not have time to revise
Hi, Jayanthi: Do you mean the shorting pin or strip at the end of a pifa? It is confusing to say x because I am not sure how to place the pifa in the coordinate. Maybe you can give me some simple drawing on it. Regards. Best regards,
pifa stands for Planar Inverted-F Antenna. This type antenna is like the ordianry patch antenna feeding with an SMA probe but with an additional shorting pin or strip at one edge of the patch connecting to the ground. So, when looking side way towards the antenna, you would appreciate an inverted-F outline. This antenna is still (...)
joelo, i knew that. anyway thanx 4 the website. is the shorting pin gives impact to the antenna bandwidth? how do we enlarge the bandwidth?
