getting a tilted radiation pattern after simulating a UHF dipole antenna
I was simulating a UHF dipole antenna on a 1U CubeSat on the software 'Ansys HFSS'. I got a tilted radiation pattern as can be seen in the image below. The reason for this was antenna ground and satellite ground were common. But there isn't anyway such that we can avoid this so please if any other solution is possible apart from disconnecting satellite ground and the antenna ground.
Please provide a solution to get back normal radiation pattern
