5GHz WiFi Antenna for Linksys EA2700?

I want to upgrade the Linksys EA2700 router, since its 5 GHz coverage is just terrible, but I can’t find an antenna anywhere, there is only 2.4 GHz. In this connection, the question is whether it is possible to put a regular 2.4 GHz antenna or is it necessary under 5 GHz? And how are they different?

The question is not specific, but still some information has accumulated. This is how regular antennas of 2.4 / 5 GHz routers look like, fed through a common feeder:
from DIR-815 -
from TP-Link N600 -
They, of course, give a conditionally circular pattern. If you need to stay with a circular one, then it is unlikely that a replacement for another of the same will significantly change something. And if you don’t like the fact that the DN is circular, then the antenna should be placed directional. You can buy it (see the link above), or most likely it will be easier to make a homemade product by counting the known designs of cans or "double square" for a different frequency.
In addition, I learned from my own experience that 5 GHz, even in an apartment, are absorbed much more strongly than 2.4 - even when moving from one room to another, the connection may break. Absorption will also be stronger in the antenna cable, so it must be of high quality and as short as possible.

All antenna elements are multiples of the wavelength (lambda), and since the wavelength depends on the frequency, the antennas will be different (5 GHz should be less)
