The Rational Design of Space Agreements: How Bilateralism Shapes Powerful States' Design Preferences

Regulation &Governance, EarlyView.
ABSTRACT The global governance of outer space relies heavily on international agreements, yet the institutional forms of these agreements remain underexplored. This article introduces a new dataset on various design features of 952 space agreements, offering the first large‐N overview of institutional design in space governance.

Circularly Polarized U-Slot Antenna [PDF]

IEEE Transactions on Antennas and Propagation, 2007
Circularly polarized single-layer U-slot microstrip patch antenna has been proposed. The suggested asymmetrical U-slot can generate the two orthogonal modes for circular polarization without chamfering any corner of the probe-fed square patch microstrip ...
