A novel dual-polarized stacked patch antenna element for wide-angle scanning Satcom on the move applications at Ka band is presented. The proposed highly integrated multilayer unit cell element operates from 27.8 GHz to 30.8 GHz with excellent scan performance up to ±60 • in both E-and H-plane. High port-to-port isolation in the entire scan volume evidences the antenna's distinguished suitability for integration into an active folded reflectarray transceiver architecture. Parasitic effects in planar array antennas degrading the intended scan volume are investigated using the infinite array analysis, and measures are introduced to suppress them efficiently. To validate the proposed antenna design several configurations were fabricated and measured successfully. The experimental results show close agreement with the simulations and indicate its excellent scanning capabilities.

INTRODUCTION T HE demand for broadband mobile satellite communication links on platforms like airplanes, trains or ships is growing for a large variety of end users [1], [2]. In mobile communication scenarios the antenna system is typically exposed to a highly dynamic environment. As a consequence, low-profile and lightweight architectures are advantageous to minimize the mechanical impact. This comes along with future satellite communication platforms tending to higher operational frequencies to meet both higher data rates and more compact antenna systems. In order to keep established communication links while moving and to avoid bulky mechanical configurations, planar concepts of electronically steerable antenna systems are of major importance [3], [4]. The proposed architecture for the active transceiver array at Ka band is based on the folded reflectarray principle [5]. The required operational bandwidth is from 29.5 GHz to 30.8 GHz with beam steering capabilities of ±60 •. The general cross section of the array configuration is depicted in Fig. 1 [6]. Considering the array in transmit mode, the primary feed antenna in the center of the array radiates an electromagnetic

“…For instance, the behaviors of the waves travelling in the direction perpendicular to the strips are utilized to design leaky wave antennas [19]. Strip-element phased arrays [20] and polarizers with low cross-polarization [21] also account for some important applications of MSG-GDS.
