Analysis of dual-frequency stacked patch antennas using subsectional bases

The analysis of stacked, microstrip patches for dual-frequency antenna applications is performed by the method of moments applied in the spatial domain and using simple, subsectional basis functions. The moment matrix is filled, and solved, quickly by exploiting symmetries and performing all computations in four-byte, single precision. The use of subsectional bases allows applications to microstrip structures of arbitrary shapes. Resonant frequencies and reflection coefficients of two stacked patches are predicted well by linear systems of surprisingly low order.<
