No, I never upgraded the Antennae on my wireless router because they are usually good enough. I don't live in a big home, and I am usually only a few feet away from my wireless router, so I rarely don't get a wireless signal unless my router is broken.
Most of my wireless wifi problems with slow speeds are from my Internet Service Provider only limiting my speed to a maximum of 15 Mbps download and 1Mbps upload speed for their cheapest broadband internet plan which cost about $30 a month for new users, and goes up in price to $60 after the first year.
