An antenna is an electrical conductor or system of conductors
- Transmission - radiates electromagnetic energy into space
- Reception - collects electromagnetic energy from space
In two-way communication, the same antenna can be used for transmission and reception
Radiation pattern
Graphical representation of radiation properties of an antenna
Depicted as two-dimensional cross section
Beam width (or half-power beam width)
Measure of directive of antenna
Reception pattern
Receiving antenna's equivalent to radiation pattern
