Why do wifi routers have multiple antennas?

Question

I know that wifi routers are essentially weak microwaves but wouldn’t multiple antennas cause interference or so?

Answer 1

Think of it like a walkie talkie/hand radio. One antenna = listen OR talk. Not both. Your WiFi box probably has two antennas. One for talking to your devices AND one for listening. It’s the same for any communication radio on trucks, planes, or whatever else.
