When using computational electromagnetics (CEM) for performance analysis of radar and high-gain microwave antennas, the necessary detailed specifications and computer-aided design (CAD) drawings of these systems are seldom readily available from the original equipment manufacturer (OEM). A reasonable estimate of the electromagnetic (EM) field levels radiated by these types of antennas may be computed...
This paper presents a top-level description of the RADARSAT Constellation Mission (RCM) Synthetic Aperture Radar (SAR) Antenna design and main operational modes and provides some Antenna RF performance predictions (gain pattern characteristics and pattern cuts).
This paper describes a metrology system for measuring deflection of a phased-array antenna panel. It will be implemented in a novel space-borne synthetic aperture radar system called WiSAR (Wireless Synthetic Aperture Radar). WiSAR uses a wireless signal interface between a boom-mounted space-feed antenna and a lightweight phased-array antenna panel. As a result of the flexible, light-weight antenna...
This paper presents a new broadband and high gain dielectric resonator for millimeter-wave underground communications systems. The proposed antenna is composed of a superstrate, an aperture coupled feed, an intermediate substrate and a cylindrical dielectric resonator. This antenna is designed to cover the ISM frequency band (57 GHz-65 GHz). This antenna was numerically designed using CST microwave...
The CSA has been working actively during the past decade on developing various technologies for improving the capabilities of SAR antennas. Various techniques have been investigated for decreasing the mass per unit of area as well as improving the electronic capabilities of the radar. These efforts were combined to form a new concept that is presented here. The concept was defined for C-band applications...
