There has been significant interest in retrodirective antennas, especially considering the
wealth of applications that could be significantly enhanced, or created, by the use of such …

This communication proposes the wideband circularly polarized (CP) phased array antenna
system for wide axial ratio scanning. For mobile satellite communication, the low-profile CP …

A 1× 3 linear antenna array consisting of Quad-Arm Curl antenna with a High impedance
surface (QACH) is presented. We believe that it is the first linear phased array solution which …

A circularly polarized multibeam antenna array based on magnetoelectric (ME) dipole is
proposed, which is fed by a substrate integrated waveguide 5× 6 Butler matrix. There are …

A circularly polarized switched-beam patch antenna array with butler matrix is designed and
experimentally demonstrated in this letter. With suitable rotation technique, circular polarized …

A wideband circular polarized (CP) switched-beam patch antenna array is presented in this
communication. The switched-beam system consists of four two-section branch-line …

We present an in-depth look at the challenges involved in using analog retrodirective arrays
for satellite communications (SATCOM). The main technical issues surrounding the …

This paper introduces a concept of a substrate-insensitive circularly-polarized phased array
for 28 GHz mobile terminal applications. Each array element is a metalized cross slot …

A 2× 16 subarray antenna design is proposed, tailored for beamforming and electronic
beam steering applications at 60 GHz for inter-satellite communication. The subarray design …

This paper proposes the circularly polarized (CP) phased array system with a pattern
optimization algorithm for low sidelobe level and scanning axial ratio. For mobile satellite …
