Electronically Reconfigurable Unit-Cell and Transmitarray in Dual-Linear Polarization at Ka-Band

Abstract : This paper presents a multilayer reconfigurable unit-cell operating at Ka-band in dual-linear polarization. It consists of a passive narrow patch and active O-slotted rectangular patch loaded by two p-i-n. diodes. These patches are connected by a metallized via-hole, and the DC bias network is routed in one intermediate layer. This unit-cell exhibits a 1-bit phase resolution for an insertion loss below 1-dB at 29.5 GHz. The interleaving technique is applied to design a dual-polarized transmitarray with independent radiation characteristics between horizontal and vertical polarizations. The -1-dB transmission bandwidth of the unit-cell reaches 7.5 % around 29.5 GHz for both polarizations.
