Radio Frequency (RF) engineering is a subset of electrical engineering that deals with devices, which are designed to operate in the radio frequency spectrum.

RF and microwave engineering is incorporated into almost everything that transmits or receives a radio wave, which includes but is not limited to mobile phones, radios, Wi-Fi and walkie-talkies, and digital satellite television.

Current research being conducted by the RF and Microwave Engineering group at UCT includes radar and sonar and defence electronics. The group is also beginning to explore research in communications, placing an emphasis on software. Further research by the group includes looking into new ways to route information around a network, specifically the software involved in receivers and transmitters.
