This Software defined radio is a radio in which some or all of their functions are software defined. Radio is a device that can transmit or receive signals in the radio frequency. The use of software defined radio (SDR) to make communications more flexible has greatly facilitated the design of cognitive radios, by making communications reconfigurable at lower layers of the networking stack. The major challenge is to design small antennas which can be operated at number of frequency bands. By tuning the frequency, single antenna can operate at different band of frequencies, for these re-configurable antennas need to be used.
