Abstract:

This paper presents the design and simulation of the proposed 15.4dBi, 8-element phased array dipole antenna at 2.0GHz for mobile communication applications using MOMNEC2 and arraycalV2.4 simulators. The paper considered the effects of changing the magnitude and phase excitation of the signal to each element while keeping the geometrical configuration of the antenna uniform. The optimized results show that the simulated value of directivity D is 15.4dBi which is 0.3 higher than the chosen design value of 15.1dBi. Also, there is a slight variation in the -3dB beamwidth values; the simulated value is 15o while the designed value is 12.7o. The analysis also show that the minimum computed SWR is 1.36dB, and the computed reflection coefficient and return loss are respectively 0.15 and 16.3dB, which show that the impedance bandwidth of the antenna is 1575- 2460MHz.
