In this paper, an Invasive Weed Optimization (IWO) algorithm has been proposed for designing antennas in broadband matching networks. The broadband matching network over the band 5-30MHz has been specifically designed based on our proposed IWO algorithm. According to the results of the optimization, we use ADS simulation software to analyze the electrical(More)
Folded dipoles are typically used as elements in curtain arrays due to their high input impedance, but under this configuration, the bandwidth of the curtain array in antenna mode is limited. This paper proposes an improved folded dipole based on a branch model, which effectively increases the bandwidth of the input impedance and decreases the VSWR(Voltage(More)
The Seeker Optimization Algorithm (SOA) is adopted to optimize the pattern synthesis of linear antenna array and the conjugate gradient method is introduced to improve the local search ability of SOA algorithm. The side lobe level, the null depth and the pattern notches of the 20 element linear array pattern are optimized. The results are compared with the(More)
In this paper, invasive weed optimization was used to calculate the p hases of adaptive antenna arrays for the purpose of placing null in the interfering direction and placing maximum power pattern in the desired signal direction to the far-field pattern. IWO algorithm will be stated and computed for this problem. The design results obtained with IWO have(More)
This paper mainly discussed the performance of loaded logic periodic antenna, and proposed an approach to calculate the loaded impedances and inductors based on our analytical results. With the use of FEKO, the accuracy of the results calculated by an analytical model is verified with simulations. Finally, the properties of the loaded logic periodic antenna(More)
