A new principle of antenna‐combining amorphous silicon solar cells and printed patches is presented. The antenna is designed, taking into account the solar cells that provide power to an MMIC amplifier. A 2×4 antenna array is presented, working at a frequency of 3.76 GHz with a bandwidth of 16% and a gain of 13 dBi (passive) and up to 30 dBi (active). The a–Si:H solar cells supply 5 V and 100 mW at AM1.5. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 29: 11–16, 2001.
