Can a Catholic woman be married by a Catholic deacon outside of the church such as in a reception site?

No. Canon 1059 requires Catholics to be married under "Canonical Form" which means in the presence of a priest or deacon (with proper delegation) and two witnesses. It is also expected that the wedding take place inside an actual church building, unless otherwise dispensed by the diocesan bishop. Why? Marriage is an ecclesial event, not a private event. The entire church gathers to witness the vows, which in themselves are a sacrament of God's love not only for the couple, but for all they encounter in their married lives. Where does the Church celebrate its sacraments? In a church. Thus, for the assurance that the event is not private, or even worse, secret, the Church insists that the event take place out in the open where everyone is welcomed to witness the vows and celebrate the sacrament they receive and become as married people. Bishops may, but are usually not inclined to give a dispensation to allow a marriage outside of a church, unless there are exceptional circumstances at play. The most common of these is that one of the parties getting married is not Christian... let's say they are Jewish, and the thought of the Jewish party's family coming into a Catholic Church where scripture would be read and Jesus Christ would be preached would be offensive to them. In these cases, all other things being equal, a bishop might be inclined to dispense with canonical form and allow a Catholic to be married at a reception site. The bishop might also be inclined to allow a Catholic to be married in a non-Catholic church before a non-Catholic minister for good reason. This would be the same kind of dispensation.
