## Design of elliptical patch antenna?

Hi , please any one tell the elliptical patch antenna design formula and how to calculate resonant frequency from major and minor axis?

## Elliptical monopole antenna

I have design the PEMA for the UHF band around the center frequency 460 MHz and I have got the results around the 456 MHz and when i am trying to check E & H field it only can radiate onto the port. Please tell me what changes should i do that will trigger the port and whole ground plane and antenna is able to radiate ? I have attached the CST File

## Antenna question - "elliptic ratio"?

In real life there is no perfect circular or linear polarized antennas, and all of the antennas are more or less elliptical polarized. I found that, especially in satellite dish antennas, the terminology of "elliptic ratio" is used, but as was stated they actually refer to "axial ratio". I think better is (to make everybody (...)

## Query regarding Circular polarisation

A simple test is using your circular one and a linear antenna. Point both one to another and rotate one of them. Connect TX to the one you rotate and the other to a RX. If you observe a constant power level, then you have a linear one and a circular one. If not, the circular is not circular, but maybe elliptical or even linear. The other question

## Polarization of antenna

The E field component was chosen to be parallel with the dipole element. The H component is therefore orthogonal or normal to it. Take care- in the "far field " only. (1,2,3) To radiate the circular or elliptical polarization of a wave, the easiest is to use the helical antenna. You can combine two dipoles with a 90-degrees phase shift to radiat

## microstrip patch antenna design

hi axial ratio is in this range:0dBelliptical polarization.

## Gain plot at multiple frequency using HFSS

Hello all, I have done parametric analysis of elliptical patch antenna. Now i want to plot gain for different resonant frequencies. Can anyone tell me how to plot gain at different frequencies using hfss? Thanks in advance !! Aarti

## Measuring the axial ratio of an antenna in CST

Hello everyone, I've designed an elliptical patch antenna in CST which works in the frequency of 5.8GHz. But I'm having problems determining whether it is radiating in circular polarization. If I'm not mistaken, for circular polarization the axial ratio must be 1 and if in ludwig coordinates, the field of vertical and horizontal must be in the sam

## Designing elliptical patch antenna using superstrate in CST

Hello, I'm trying to improve the gain of my antenna using superstrate. I read a few journals regarding this topic but i could not determine the thickness of the superstrate needed. The frequency that i need to obtain is 5.8GHz and i'm using coaxial feed. This was one of the papers i referred. The thickness of my ground plane is 0.035mm, substrate

## truncated circular patch antenna

can u tel me what formulas used to find the resonating frequency or radii(elliptical patch antenna)...?? is it different from when we analysis for truncated elliptical patch antenna....

## Cross polarization Antenna

Rain does not consist of round droplets but have more elliptical size and are tilted (due to wind). So when you excite a rainy area with a vertical polarized wave, the induced current in the rain droplets may have a (small) horizontal current component. This reradiates and creates a horizontal polarized EM wave component. This component couples

## design of monopole antenna

googled this: I guess the ideal is in the paper... just add a gnd plane to get a monopole.

## Elliptical Patch Antenna

Can anyone please design for me an elliptical patch antenna working at 1.5-2.5 GHz. I'll be grateful. Contact -

## design equations for elliptical patch antenna

i am doing a project on elliptical patch antenna.i need design equations and calculations please give me any advice for this

## pls help to design an uwb antenna using Hfss

Ultra Wide Band antennas in PCB can have an elliptical 2D form, for instance. You can find some HFSS tutorials, as starting point to know how to use the software. Ex. em: talk - HFSS Tutorial 1: Microstrip Patch antenna

## hfss microstrip patch antenna at 5.83GHz coaxial feed elliptical patch

I found the document attached online on how to design a rectangular microstrip patch antenna using a coaxial feed. Just go through the design procedure and modify it for elliptical patch. And go through some books of microstrip antenna design, you might find exact design procedure on how to determine the location of the feed point for the (...)

## planar Elliptical monopole UWB antenna using HFSS

Hi, I am a newbie to this forum and also to using HFSS for antenna design. I have simulated a design using HFSS and still unsure whether the antenna can be used within the UWB range. So far, I have the VSWR, s11 and Gain radiation patterns in DB from 2-11 GHz(attached). I need advices/suggestions on how to improve on my design, how to plot radia

## How to know the polarization of my antenna?

Hi All, I designed an UWB antenna Using HFSS. Is there any way that i can check the polarization of my antenna (e.g circular-linear-elliptical)?
