Hi,
there is something i don't understand about microstrip antennas.
suppose that i'm designing a patch antenna with a resonant frequency of 2.4 GHZ, does it mean that input impedance of that antenna should be PURELY real at 2.4 GHZ at the edge?
i tried simulating this using a single patch using...
Re: How to increase the bandwidth of the microstrip patch antenna array in ADS
Hi thanks for the help
here's my feed network, its consists of 100, 50 and 70 (quarter length match) ohm Tlines, from a quick observation can you see any flaws in the design?
or do you have any suggestions of how...
How to increase the bandwidth of the microstrip patch antenna array in ADS
Hi,
I'm designing a 4X1 microstrip patch array antenna (microstrip line feed) at 2.4-2.5 GHZ band using ADS
the parameters i m getting are
returnloss = -25.8 db
directivity is 12.65 dbi
gain= 12.7dbi
the problem is that...
Hi,
I'm designing a 4x1 microstrip array (attached a snapshot) that suppose to work in the 2.4-2.5 GHZ band, i chose my resonance frequency at 2.45GHZ, Er=2.2.
I'm getting pretty good results, both gain and S11 - (-38 dB), but my bandwidth is too narrow.. how can i increase it so it'll cover...
Hi,
I'm a beginner at using ADS, i'm using this software for my final year's project to design a Microstrip patch antenna 4X1 array,
and i'm trying to figure out what are my antenna's properties (gain, directivity, etc.) using ADS.
I've noticed there are two optional simulators for obtaining...
after testing many feed positions the best i've got was -9 dB with a pure real Zin or 32 Ohm, and after i've matched it with a 1/4 wavelength TL i was able to get a -25 dB S11, (3.16e-3 unitless)
does such a result (-25dB) considered a good matching?
many thanks for the help. :-)
if that's my input impedance how do i match it to a 50 Ohm TL using a 1/4 waveguilde? (can only match it with a real impedance) do i need take only the real part (286 Ohm) for the matching
or do i need to find a spot on the antenna where my impedance is real and from this point do the matching...
Hello,
I want to determine the input impedance of a patch microstrip antenna (W=49.41mm L=41.76mm, er=2.2) by using ADS Momentum, how can i achieve this?
i need it so i can match the antenna to a 1/4 wavelength transmission line.
I'v done a simulation in ADS Momentum and it shows that the...
Hi,
I'm a senior EE student and i was given a final year project in the field of antenna communications. i seek your help regarding how to start doing this project.
The goal of my project to develop and manufacture a printed antenna for WLAN applications using Agilent's ADS.
the printed antenna...
