What you’ll want to replace is the Diversity Antenna. If you’re also having issues with Wi-Fi/BT, this could resolve those issues too.

I had the exact same issue. I replaced the Wi-Fi diversity antenna on my iPhone 8 (not the 8 Plus) and that didn't fix the issue. Rather replacing the top left antenna fixed my reception issue. Be super careful about the hidden screw on the side of the phone housing, it's a little bit difficult to see but as long as you have decent lighting like a lamp (like I used) then you should be able to see it. It's a little bit fiddly but not too awkward to take out the screw and put it back in but spending money on a replacement top left antenna is definitely better and way cheaper than buying a new phone. Details on how to replace your top left antenna are quite self explanatory but you can take a look on the iPhone 8 Charging Port replacement guide on iFixit:

update: I just realised there's also a full guide on replacing the top left antenna.

I had the same issue. I replaced the down right antenna firstly and that didn't fix but top left. Thanks for sharing your experience about it Jordan Win!
