This paper illustrates the use of Characteristic Mode Analysis in FEKO to synthesize a desired combined antenna pattern of multiple antennas mounted on an aircraft, and to mitigate co-site interference between antennas on an aircraft.
A systematic approach in developing a 4-port structural antenna system on a Small Unmanned Aerial Vehicle (SUAV) is presented. The largest dimension of the SUAV is 0.67 wavelength of the operating frequency. Using Characteristic Mode (CM) Analysis, two significant CMs with good radiation efficiency are identified. The radiation patterns of these two CMs can be synthesized by combining the individual...
The paper discusses the application of the Characteristic Mode Analysis (CMA) to a number of problems arising in practical antenna applications, and identifies some challenging issues that have been encountered by in the process of applying the CMA to some real-world problems. These include, among others, excitation of the Characteristic modes on complex platforms; antenna placement on these platforms...
