A High Gain Deployable L/S Band Conical Helix Antenna Integrated With Optical System for Earth Observation CubeSats

Rapid Deployable Antenna Concept Selection for Cubesats

In this paper, we present a new graphical tool for the preliminary design of deployable CubeSat antennas aimed at coupling electromagnetic and structural antenna design. The proposed methodology predicts antenna performance characteristics using analytical expressions and compares them graphically against antenna geometric parameters. Such a technique allows the comparison and analysis of sever...

Hybrid optical antenna with high directivity gain.

Coupling of a far-field optical mode to electronic states of a quantum absorber or emitter is a crucial process in many applications, including infrared sensors, single molecule spectroscopy, and quantum metrology. In particular, achieving high quantum efficiency for a system with a deep subwavelength quantum absorber/emitter has remained desirable. In this Letter, a hybrid optical antenna base...

High Gain Conformal Tri Band Antenna

In this paper, a tri-band E-shaped microstrip patch antenna is presented for SHF and microwave data links. The proposed antenna has symmetrical properties and has been designed by forming E-shape structure on substrate with Wave guide feed. It radiates for three bands having two bands in SHF and one in lower EHF frequency bands. It is demonstrated that the fabricated antenna offers improved val...

Suitability of Nickel Chromium Wire Cutters as Deployable Release Mechanisms on CubeSats in Low Earth Orbit

This paper investigates the suitability of a nickel chromium wire cutter (NCWC) for use on the GASPACS (Get Away Special Passive Attitude Control Satellite) Mission. It is intended that when activated the NCWC will cut through a restraining wire and thereby release the stored energy of the deployable AeroBoom. Flight worthiness is based on favorable performance during functional testing to addr...
