Design of concentric circular antenna for multiband applications

Abstract

Design of Concentric Circular Antenna for Multiband Applications should be presented in this paper. In this paper the concentric circular antenna has been designed and propound and then operates at S, C, X, Ku, K, Ka and Q bands. In order to improve the radiation characteristics the concentric slots are introduced. The designed antenna operated at a frequency from 1 to 40 GHZ for return loss-10dB. The designed antenna substrate length (L1) and width (W1) are 34 mm x 36 mm and it coated with FR4 epoxy material. The line capacitance and inductance of circular patch are increased by use of concentric circular slots. The concentric circular antenna is studied and simulated to operate at seven different frequencies at 3.43GHZ, 7.63GHZ, 10.51GHZ, 15.98GHZ, 24.58GHZ, 30.28GHZ and 35.67GHZ. The concentric circular antenna uses HFSS v.13.0 (High Frequency Structure simulator) for design and simulation purposes.
