Dual band independent phase shift electronically reconfigurable transmitarray for Ku band

In this article, we presents a high gain low profile and compact dual band with independent phase control transmitarray unit cell in Ku-band. Independent phase shift and polarization control antenna array develops for many communication applications like satellite communication, mobile communication and SATCOM on the move etc. A dual band independent phase control transmitarray (DIPCTA) develops at 12.5/16.5 GHz with dual linear polarization. There are two pin diode (active) loaded patches are composed to control the uplink and down link frequency bands. Two parasitic off set feed patches place over Receiver (Rx) side to transmit energy through Vias to Transmitter (Tx) side. There are four states available for insertion losses and phase distribution control for each upper band and lower band frequency. Upper band achieved min theoretical insertion losses 0.74 dB approximately. Lower band theoretical minimum insertion losses obtain 1.34 approximately due to four-pin diode at same side. 180-degree phase shift achieve for upper and lower band control states independently.
