A novel compact broadband and dual‐polarized Ku‐band synthetic aperture radar (SAR) antenna with a high level of isolation between polarizations has been developed by INTA Radar Laboratory as an advanced sensor for the QUASAR project, which involves INTA new SAR developments for small platforms and unmanned aerial vehicle (UAV). The antenna design is composed by a 4 × 8 dual‐polarized square patch...
This paper describes a novel synthetic aperture radar (SAR) antenna design in Ku Band. This antenna is an 8 times 2 array composed by a waveguide feeding network in order to support high-level input power, and multilayer stack patches which are exited by electromagnetic coupling from the waveguide through a resonant iris with dumbbell shape. Both polarizations (linear horizontal and vertical) have...
In this paper the design of an antenna for a signal identification system which works at 1.06GHz is presented. The system requires reduced dimensions because this antenna must be placed on an airplane. The structure is based on a multi-layer configuration with double stacked patch fed by a coaxial probe. Low-cost material has been used.
The design of an antenna for a Signal Identification System which works at 1.06GHz with a bandwidth of 80 MHz is presented. The maximum gain value of the total antenna required is 16.6 dBi. Moreover, a plusmn50deg sweep of the aiming angle signal with a 3 dB level loss in the edges is desired. The structure is based on a multi-layer configuration with double stacked patch fed by a coaxial probe and...
