Dear vfone,
Could you please help me check this post about UWB/SWB antenna design?
Thank you very much!

Yes, I also doubt that this research work was done properly from the designs in Figure 3 of the reference paper [1].
The reference patch antenna in Figure 3 of [1] is a normal planar rectangular-shape monopole antenna. K. P. Ray gave the empirical formula for initial design of the normal planar...
Dear friends,
The reference paper [1] reports an antenna that could operate in the frequency range of 0.1 - 30 GHz while the size is 60 mm x 60 mm x 1.6 mm.
I found the results of the reference paper [1] were very exciting and I tried to follow the paper by simulating the antenna in HFSS. All...

Hi,volker@muehlhaus, thank you very much for your response.
Following your valuable suggestion, I got the correct results. The mistakes are made for the port setting in the simulation. Because this is a finite GND, the pin+ should reference to the
explict reference pin-.
Yes, I want to check...
For True Large Signal Differential Input Impedance Evaluation, we must use the true differential mode and the VNA must support true differential mode, that is to say, every port of VNA must have its own VSG and VSA...
Dear All,
I want to use ADS2016 from Keysight to Co-Simulate the PCB layout with RLC.
But for the first step, I found the layout simulation results were not believable.
The real part of the impedance of the pad directly connected to the GND plane seems to be too large,
is about 27.8Ω...
