Abstract: An analysis of a general circular sector microstrip antenna (CSMA) with sector angle, ⍺, is presented in this paper. The theoretical analysis is carried out by applying cavity model-based modal expansion technique. The computed results are validated with measured results for CSMA geometry with ⍺ = 60º. The computed results show a fairly good agreement with measured results. A reasonably small deviation of 1.06% in the resonant frequency is recorded, while a fairly good agreement between measured and computed return loss and radiation patterns is recorded. This validates the proposed technique of treating CSMA geometry.
