Focused transmitting array antenna at 5.8GHz for wireless power transmission

In this paper, two kinds of high gain and low sidelobe emission array antennas are presented. The two kinds of array antennas are designed by dloph-chebyshev synthesis and Taylor synthesis respectively, microstrip array antenna is obtained by designing microstrip feed network with unequal amplitude power divider. The simulation results show that the transmitter array antenna using dloph-chebyshev synthesis method at 5.8GHz has 23.2 dBi gain, the beam Angle of plane yoz and xoz is respectively 12° and 12°, and the transmitter array antenna using Taylor synthesis method at 5.8GHz has 23.3 dBi gain, the beam Angle of face plane yoz and xoz is respectively 11° and 12°, two kinds of high gain and low side lobe emission array antennas have good performance. They can be used in wireless energy transmission.
