Antimagic Field states (emphasis mine):
An antimagic field suppresses any spell or magical effect used within, brought into, or cast into the area, but does not dispel it. Time spent within an antimagic field counts against the suppressed spell's duration.
This means that Antimagic Field only suppresses a magical effect in these three cases:
- The effect is used within the field (such as a caster attempting to cast a spell or use a supernatural ability).
- The effect is brought into the field (such as a buff on a fighter that runs into the area).
- The effect is cast into the field (such as a fireball being cast into the field).
Given that in our scenario, the wizard is not within the field when they cast the relevant spell, #1 does not apply. Given that the duration of the spells are instantaneous, #2 does not apply. This means that we only need to prove that #3 doesn't apply.
The rules for Aiming a Spell state:
You must make choices about whom a spell is to affect or where an effect is to originate, depending on a spell’s type. The next entry in a spell description [after range,] defines the spell’s target (or targets), its effect, or its area, as appropriate.
If we then look at the relevant portion of Dimension Door, it says:
Target you and touched objects or other touched willing creatures
This means that dimension door is cast on the creatures, not into the Antimagic Field. Therefore, #3 does not apply. Since none of the statements for spell suppression are true, dimension door (and teleport which has a similar targeting line) allows you to teleport into an Antimagic Field.
If the reader is still doubtful of the above, there's no need to look anywhere else for more proof of how they interact. Antimagic Field also states:
The effects of instantaneous conjurations are not affected by an antimagic field because the conjuration itself is no longer in effect, only its result.
Since Dimension Door and Teleport (plus variants) are instantaneous conjurations, they would work even if they did target the area of the Antimagic Field.
