“…The analysis gives the frequency-dependent network matrix for the array with arbitrary terminations and has been used in the design of multiple-device oscillator powercombining circuits [8]. The analysis makes no assumptions about array symmetry or the nature of the current density on the surface of each antenna.…”

A theoretical and experimental study of strip dipole antennas located on a supporting dielectric slab mounted transversely in rectangular waveguide is presented. Galerkin's method is used in the full-wave solution of an integral equation for each antenna's surface-current density using the Green's function for the slab-loaded waveguide. The paper is motivated by the need for multiport-network models to aid the development of multipledevice power-combining circuits in rectangular waveguide. The design data presented here for single antennas should prove useful for planar-mixer and oscillator circuits. The presence of slab modes is noted and the slab-mode resonant frequencies are predicted. Validation of the numerical models is provided by scattering experiments on the shorted antennas, and excellent agreement is obtained in the range of 8.0-12.5 GHz.
