Digitally Excited Reconfigurable Linear Antenna Array Using Swarm Optimization Algorithms
This paper describes the synthesis of digitally excited pencil/flat top dual beams simultaneously in a linear antenna array constructed of isotropic elements. The objective is to generate a pencil/flat top beam pair using the excitations generated by the evolutionary algorithms. Both the beams share common variable discrete amplitude excitations and differ in variable discrete phase excitations...
متن کاملOptically Reconfigurable Gate Array
Reconfigurable processors, like the Field Programmable Gate Arrays (FPGA's), open new computational paradigms where the processor is able to tailor its internal structure to better . implement a given application. A typical FPGA consists of an array of configurable logic blocks and a mesh of interconnections fully programmable by the user to perform a given application. By just changing its int...
متن کاملOptically Controlled Phased - Array Antenna Technology for Space
Using MMICs in phased-array applications above 20 GHz requires complex RF and control signal distribution systems. Conventional waveguide, coaxial cable, and microstrip methods are undesirable due to their high weight, high l o s s , limited mechanical flexibility and large volume. bution in MMIC phased array antennas, is optical fiber. Presented are potential system architectures and their ass...
متن کاملReconfigurable Antenna Aperture with Optically Controlled GeTe-Based RF Switches
We have characterized the ON state DC electrical resistivity and OFF state capacitance of GeTeBased RF Switches under direct optical laser excitation. Our tightly-coupled dipole array exhibits performance in excess of 4 to 1 bandwidth over wide-scan angle up to 60 degrees with in-band rejection capability using reconfigurable baluns. Integration of optically-controlled GeTe-Based RF switches at...
متن کاملHybrid Array Antenna for Broadband Millimeter-wave Applications
A hybrid array configuration suitable for wideband millimeter-wave applications is presented in this work. The proposed structure is based on the use of circular waveguide elements electromagnetically coupled trough circular apertures to a stripline distribution network. The adopted excitation mechanism avoids the use of transition components generally reducing the overall antenna efficiency. S...
