Abstract

In this paper, Cuckoo search optimization algorithm based placement of tasks in FPGAs is introduced and was compared with PSO, ARPSO and GSA. Both single and multiobjective constraints based fitness function is formulated. The simulation result shows that CSO outperforms the others. By tuning the design parameters of CSO algorithm, the FPGA Placement process performs better.

Abstract

Objective: The different configurations of hexagonal monopole antennas are designed, simulated, tested and their performance is compared. Method: Different Hexagonal monopole antennas are designed and simulated using HFSS, these antennas are designed using Defective Ground Structure (DGS) and slots are made in ground plane and on patch. Effect of slot position on performance of antenna is examined. The antenna units are studied through simulation two antennas were fabricated and its return loss and VSWR are measured. Findings: The antenna parameters like return losses, VSWR, Gain and Directivity are evaluated and return losses and VSWR for the fabricated antennas are measured. It is observed that over a wide frequency band the return losses are <10 dB and VSWR is less than 2. Applications: These antennas can be used over UWB for Wireless and Indoor applications.
