چکیده
We demonstrate a silicon (Si)-gallium arsenide (GaAs) semiconductor-based holographic metasurface antenna operating at 94 GHz. The molds the radiated beam by resorting to approach involving modulation of guided-mode generated pillbox beamformer. beamformer is fed three integrated horns in substrate-integrated waveguide (SIW) technology located focal plane parabolic reflector correspond independent beams and allow steering switching from one feed another. proposed planar extremely low-profile, thus suitable for small platforms such as CubeSats/SmallSats. A prototype validates concept demonstrating directivity high 31.9 dBi reflection coefficient lower than -15 dB

Design of Rotman Lens Antenna at Ku-Band Based on Substrate Integrated Technology
In this research work, a multibeam antenna which is a combination of a beamformer network (BFN) and a linear array antenna, has been designed. A Rotman lens has been chosen as beamformer network and Vivaldi antennas have been selected for constructing array antenna. The Substrate Integrated Waveguide (SIW) was used for implementing Rotman lens. After explanation the structure of Substrate integ...
متن کاملMAC Layer Performance with S teerable Multibeam Antenna Arrays
In this paper, we are concerned with the performance at the media access control (MAC) layer of the protocol stack when multibeam adaptive antenna arrays are employed at the base station site. Specifically, we analyze the performance of slotted ALOHA when the base station receiver uses multibeam antenna arrays capable of steering the beams selectively on smaller sectors. The effect of different...
متن کاملA New Metasurface Superstrate Structure for Antenna Performance Enhancement
A new metasurface superstrate structure (MSS)-loaded dual band microstrip line-fed small patch antenna is presented in this paper. The proposed antenna was designed on a ceramic-filled bioplastic sandwich substrate with a high dielectric constant. The proposed 7 × 6 element, square-shaped, single-sided MSS significantly improved the bandwidth and gain of the proposed antenna. The proposed MSS i...
متن کاملReconfigurable MIMO Antenna Design with High Isolation using Metasurface
In this paper, a frequency reconfigurable multiple-input-multiple-output (MIMO) antenna has been described. The idea of the design is to form reconfigurable MIMO antenna by the development of two-port antenna that are identical to each other and pin diodes are used to achieve the frequency reconfigurability. The design of the canonical element consists of compact folded slots with one pin diode...
