Antenna Design Based on the Conductor-Backed Asymmetry CPW Structure with Finite Ground Planes and Substrate

Based on the conductor-backed asymmetry CPW structure with finite ground planes and substrate, a printed antenna resulting from equivalent magnetic current loop is proposed. At 2.4GHz, the proposed antenna can be designed inside an area of 10 mm x 10mm. Binary particle swarm optimization and square metal mesh are employed to optimize the |S11|. Antenna efficiency can be further improved by including this parameter into the cost function of the optimization.
