In this paper a shorted planar meander-line metal antenna (SPMMA) is designed at 2.45 GHz by modifying the radiating element of a shorted planar rectangular metal antenna (SPRMA). The shorting strip reduces 40% size of the meander-line antenna and the size of the SPMMA is 16% shorter compared to that of SPRMA. The reflection coefficient, gain and efficiency of the SPRMA and SPMMA are compared. The...
In this paper a parametric study on characteristics of a planar metal antenna in vicinity of a homogenous human head at 900 MHz and 1800 MHz are carried out. Initially the planar metal antenna is designed at 900 MHz and 1800 MHz. The impedance and radiation characteristics of these antennas are shown in free space and in proximity of a human head. Also Specific Absorption Rate (SAR) for different...
