  Wormholes (WHs) are considered as hypothetical shortcuts or tunnels in
spacetime. In general relativity (GR), the fundamental ingredient of WH
geometry is the presence of exotic matter at the throat, which is responsible
for the violation of null energy condition (NEC). However, the modified gravity
theories has shown to be able to provide WH solutions satisfying energy
conditions (ECs). In this paper, we study the static spherically symmetric WH
solutions in modified $f(R,T)$ gravity for a phantom fluid case. The exact
solutions of this model are obtained through the equation of state (EoS),
$p=\omega \rho$, associated with phantom dark energy (DE) $\omega<-1$. We find
the existence of spherically symmetric WH solution supported by phantom energy
distribution. The shape function of the WH is obtained in this model obeys all
the WH metric conditions. In modified gravity scenario the phantom fluid WH
violates the NEC in radial case, unlike in the tangential case. Furthermore,
using the "volume integral quantifier" (VIQ) method, the total amount of EC
violating matter in spacetime is discussed briefly.
