Abstract: A rigorous theoretical analysis of a circular sector microstrip antenna with sector angle ⍺ is carried out. General expressions for radiated fields by antenna are derived by applying cavity model based modal expansion technique and are used to study its radiation parameters. Similar to a circular disk antenna, better results for circular sector antenna are also obtained in TM11 mode of excitation. The computed results of a sector antenna with ⍺ = 60º are compared with simulation results and a difference of 2.5%, 38%, 7% and 1.9%, respectively in resonance frequency; input impedance, directivity and bandwidth is recorded.
