Abstract

A linear array of capacitively loaded, electrically small conducting loops is modeled using the method of moments (MoMs) for a practical finite length array and an analytical approach for an ideal infinite length array. The complex propagation constant kg = β . jα is modeled. When the wave number β crosses below the free space value k0, a leaky wave is triggered. This leaky mode antenna radiates omnidirectionally in the ñ direction. The beam angle and beamwidth are determined from β and α and respectively. The complex propagation constant found using the two methods (i.e., MoMs and analytical method) agree where computational extraction is possible.
