The design of a Ka-band coplanar waveguide slot-coupled patch antenna ESA with integrated MEMS phase shifters has been described above. The incorporation of MEMS phase shifters into the ESA design results in a compact, efficient uplink mechanism for a future Army satellite communication system. A control board for biasing the phase shifters and initiating beam steering will be incorporated into the...
A VHF bent monopole antenna mounted on an Army UAV wing platform is modeled and simulated using the FEKO electromagnetic simulation software package and the results are compared with measured radiation pattern data. In order to reduce the complexity of the final FEKO simulation and minimize its runtime and memory usage, the simplification of the composite wing structure as a PEC wing is verified through...
This paper discussed about the successful simulated and measured data of the wafer-scale CPW slot-coupled Ka-band patch antenna presented above strongly advocate its candidacy for future integration with a MEMS-switched control board. Since it is a single-layer embodiment of the slot-coupling feed method, the total system weight is minimized and the complexity of the wafer-scale fabrication process...
In this paper, a symmetrical 1.5 GHz patch antenna has been designed, constructed, simulated and experimentally fine-tuned to be the radiating element in the experiment to implement direct antenna modulation. With a resonant bandwidth of about 30 MHz (using a 10 dB or better return-loss standard), there is significant room for improvement that direct antenna modulation can offer to the information...
