Antenna Design

Delcross Technologies provides engineering services for designing antennas using both full wave and asymptotic computational electromagnetic (CEM) techniques.

Tools such as NEC, SAVANT and WIPL-D have been used to design a wide variety of antennas including Yagi-Uda, Log Periodic Dipole Array, Cassegrain Reflector, Corner Reflector, Phased Arrays and several other types of antennas.

Design solutions take into consideration typical antenna design parameters such as input impedance, VSWR, directivity, front-to-back ratio, side lobe levels, mutual coupling, bandwidth and beamwidth.

Installed Performance

Antennas installed on a platform such as an air, ground, sea or space vehicle can have drastically different performance compared to their free space performance. These changes in performance are due to interactions with the platform. For example, phenomena such as multipath and creeping wave can significantly change the radiation pattern of an antenna. So, one may have an antenna that performs very well in free space, but when the antenna is installed on their platform of interest, the performance may no longer be acceptable.

Simulation tools can be used to quantify the installed performance of antennas on platforms. Tools such as NEC, SAVANT and WIPL-D can be used to compute installed radiation patterns, input impedance and mutual coupling (for arrays). We have successfully used these types of tools to predict installed antenna performance on air, ground, sea and space vehicles as well as on buildings.
