## PIFA coaxial Feeding

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 (...)

## Designing PIFA shorting Pin in HFSS

The layout shown, can result in a good antenna when measures are well chosen. The resonance at 7 GHz is likely due to a higher resonating mode. For example a quarter wave whip that is resonant at say 300 MHz, can also resonate in a 3/4 wavelength mode (around 900 MHz), but the radiation pattern is different. You can see this from the current di

## How to calculate impedance of PIFA

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.

## Help me with the monopole simulation (HFSS)

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 (...)

## How to enhance the bandwidth of PIFA

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

## reg fabrication work -PIFA-to jain sir

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. (...)

## reg-fabrication work for PIFA antenna(very urgent)

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 (...)

## to jain sir(reg--fabrication work)--------PIFA antenna

hi sir, For doing fabrication work, first step is preparing mask, for that the people whoever is preparing mask they are asking AUTOCAD daigarm. In my case i am pifa antenna is having groundplane ,patch,shorting pin and the probe feed is connected between ground plane and the radiating patch. suggest me . i can prepare mask (...)

## reg PIFA to JIAN sir

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

## Establishing the length of the short in PIFA

iam jayanthi i need a help from most of the papers(on pifa) they are not mentioning the length of the short that is in X axis.they are mentioning only the height and the width of the using which option we have to draw the shorting post. what i followed to draw the shorting post is,first i will select the portion actually where i

## Looking for info about PIFA

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 (...)

## Whats the difference between PIFA and IFA?

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?
