Ultra-Wide Band (UWB) Ice Cream Cone antenna for communication system

The objectives of this paper are to design, fabricate and analyze UWB Ice Cream Cone Antenna. This antenna was fabricated on FR4 substrate. The effect of varying parameter for length of rectangular is studied. This antenna occupies the entire 3.1 GHz to 10.6 GHz spectrum band. The designs are simulated using CST Microwave Studio Simulation and the measurement are successfully achieves UWB spectrum band requirement. The proposed antenna suggested that the return loss must be less than -10 dB and a VSWR of less than 2 throughout the entire band with a lightweight planar profile and omnidirectional radiation pattern. The UWB Ice Cream Cone Antenna is designed, fabricated, measured and managed to cover UWB bandwidth from 3.1-10.1 GHz with the VSWR between 1.18 - 1.7 with a small size of 40 x 25 mm2 . The sizes of UWB communication devices can be reduced by using the Ice Cream Cone antenna. In the future, the low loss substrates can be used in order to increase the Return Loss of the antenna at higher frequencies for wideband applications

Route Planning Analysis In Holes Drilling Process Using Magnetic Optimization Algorithm For Electronic Manufacturing Sector

Electronic manufacturing sector uses computer numerical controlled machines for drilling holes. Most of the computer numerical controlled machines used nearest neighbour algorithm to plan the route for the drill bit to travel. Based on this motivation, this paper proposes an approach which is based on the experimentation of Magnetic Optimization Algorithm. In this implementation, each magnetic agent or particle in Magnetic Optimization Algorithm represents a candidate solution of the problem. The magnitude of the magnetic force between these particles is inversely proportional to the distance calculated by the solution they represented. Particles with greater magnetic force will attract other particles with relatively smaller magnetic force, towards it. The process is repeated until the stopping condition meets and the solution with lowest distance is taken as the best-found solution. Result obtained from the case study shows that the proposed approach managed to find the optimal solution. With this method, electronics manufacturing sector can optimize the drilling process hence will increase the productivity of the manufacturer. This study can be extended further by tuning the parameters of MOA in order to enhance the drilling route process
