In this paper, four different weighted sum approaches for the PSO (Particle Swarm Optimization) fitness function to design wideband medium gain antenna are investigated and compared. A linear 4 element microstrip antenna is chosen as benchmark structure to test the performance of the four PSO fitness functions. The results clearly show that all the tested fitness functions achieve a similar global...
A novel two-dimensional wideband array of microstrip E shaped patches is designed for use in a 10 % frequency range around the 2.45 GHz ISM band. The main design criterion was a combination of this bandwidth with an aperture efficiency as high as possible, since this allows to minimize occupied space. The maximum aperture efficiency of the array achieved by CST MWS and in the measurements is 78 %...

Three novel two-dimensional wideband arrays of microstrip E shaped patches are designed for use in a 10% frequency range around the 2.45 GHz ISM band. The proposed arrays are intended to serve as subarray in a switchable outdoor antenna that has to be low-cost and very compact. The scan in the horizontal plane is performed by using switching between six subarrays covering 180 degrees. The main design...
