I thought the same too...and was actually going to go one step back and simulate the loops with a wire diameter of 10um instead of a flat metal of 10um...will post my observations once I get to it.
The loop is just in air. I do intend to print it later on a substrate but the simulation on the substrate din't make sense so I was simplifying things and first studying it in air.
Since i intend to print it on a substrate ...the loop is really a flat metal with a 10um width and the operating...
the radiation pattern is the normalized power distribution which is defined as the vector cross product between the electric field and the magnetic field. This does not have to necessarily be the same as that of either the electric field or the magnetic field. In other words if in a particular...
I looked at the magnitude current distribution and it looks more of less constant through out the loop...however when I looked at the vector current distribution I noticed that there are two vectors pointing in a plane almost at 45deg to the plane of the loop, right where the opening in the loop...
Yea, when I use a dipole antenna the radiation pattern is correct..i.e a torus around the dipole.
I also increased the size of the loop..i.e >0.1 lambda...but no luck
I also increased the size of the radiation box...and even changed the shape to a sphere instead of a rectangular box...but...
Hi all,
I have designed a loop antenna in HFSS using a lumped port. I was observing its radiation pattern in the far field region and noticed that HFSS gives a maximum in the plane perpendicular to the plan of the loop antenna and a null in the plane of the loop antenna. Which should infact be...
