Hi, After designing an antenna in hfss. How can I be shure if my design is well adapted? For exemple, if I designed a patch antenna with microstrip line of 50 ohms, should I go simulate to see if the antenna impedance is equal to 50 ohms for all the (...)
Hello, I wanted to know if it is possible to design a patch antenna with operating band 60 MHz to 70 MHz in hfss. If yes, what will be the estimated size required. please reply as soon as possible. Thank you
In this design, first resonant frequency is at 12.5 GHz. You can bring down resonance at 12 GHz just by slightly increasing patch antenna length. dB valuse are not clear as there is no 'Y-axis' value in graph.
Hello evey body, Anybody can help me i'm a student and i'm new with hfss and patch arrays. i would like to Match 50 Ohm line to 50 ohms patches in my feed network of 2*2 microstrip array but i can't how can i do it and how can i design the Feed network. if any body have a picture which include the impedance of each (...)

Hy every one. I am new in LTCC. I have designed patch antenna in hfss before using Rogers substrate 1.5mm thick. Now I want to design it with LTCC material. But I don't know how to choose LTCC substrate and how to design such antenna in hfss :-? . Anyone (...)
hello.. im designing frequency reconfigurable patch antenna at frequencies 2.45,5.5 and 7.5GHZ in hfss using pin diodes. i have assigned lumped RLC boundary to pin diodes.but im not getting exact frequency resonance. can anyone help me how to use pin diodes is biasing also required for pin diode??
Interesting planar antenna design, but certainly not a patch antenna.
please tell me how to design the feed length of co axial port in hfss , is it effect the gain of patch antenna. when i change the feed length my gain is varies or it depend upon the frequency. also give me the formula for calculating that. thanks
I am working on hfss designing of patch antenna. Here in the design when it is simulated it sometimes completes adaptive pass and does the analysis but the same design if I close and open and re validate and run then it shows conversenge problem. Again if I save the file in some other (...)
