Analysis of a Microstrip Reflectarray Antenna for Microspacecraft Applications
نویسنده
چکیده
A microstrip reflectarray is a flat reflector antenna that can be mounted conformally onto a spacecraft’s outside structure without consuming a significant amount of spacecraft volume and mass. For large apertures (2 m or larger), the antenna’s reflecting surface, being flat, can be more easily and reliably deployed than a curved parabolic reflector. This article presents the study results on a microstrip reflectarray with circular polarization. Its efficiency and bandwidth characteristics are analyzed. Numerous advantages of this antenna system are discussed. Three new concepts using this microstrip reflectarray are also proposed.

Ring Shaped Compact Microstrip Reflectarray Antenna
Regularly shaped compact microstrip antennas have a small size but their gain is insufficient for most applications. Therefore, a ring-shaped compact microstrip reflectarray with microstrip antenna feed has been proposed. Different configurations, namely, 1 × 3, 3 × 1, plus-shaped and 3 × 3 have been analyzed. The 3 × 3 configuration yields an optimum gain of 10. 8 dBi and a narrow beamwidth of...
متن کاملA Varactor Loaded Reflectarray Antenna
A new approach for beam steering in reflectarray applications is introduced in this paper. The progressive phase distribution is achieved by loading each microstrip patch element with a varactor diode on the radiating edges. The scattering characteristics of a single varactor loaded patch will be first presented. Then, as a test of the beam steering capability, a five elements linear reflectarr...
متن کاملA Capacitive Fed Microstrip Patch Antenna with Air Gap for Wideband Applications (RESEARCH NOTE)
In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...
متن کاملReflectarray antennas for terahertz communications
Reflectarrays composed of resonant microstrip gold patches on a dielectric substrate are demonstrated for operation at terahertz frequencies. Based on the relation between the patch size and the reflection phase, a progressive phase distribution is implemented on the patch array to create a reflector able to deflect an incident beam towards a predefined angle off the specular direction. In orde...
متن کاملA compact stacked Quasi-fractal microstrip antenna for RFID applications
In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
