C-Shaped Complementing Patch Antenna for Broadband Communications

ABSTRACT

Design of an optimized planar coplanar waveguide (CPW) fed complementing C-shaped patch antenna for broadband communication is presented. It resonates at 2.1 GHz with bandwidth spanning from 1.2 to 2.45 GHz for the return loss of −10 dB or more. In the absence of closed form design formulae for its resonant frequency, this paper proposes use of either artificial neural network (ANN) or simulated annealing (SA). Results from these stochastic methods are in good agreement with those from electromagnetic (EM) simulations as well as prototype measurements. The EM simulations show good radiation characteristics and moderate gain in the entire operating band of the antenna.
