The use of information and communication technology is growing throughout society and world, A new products and solutions are developed at an increasing rate. Also half-wave dipole is the most common antenna in recent year, This antenna is used in all transmitters that are broadcast in all directions the parallel to the surface of the ground or in the receptors that pick up signals from all directions this work designed a new half wave dipole antenna and planar dipole antenna using the high-frequency structural simulator (HFSS software is used for the simulation and design calculations of the dipole antennas. The half wave length dipole antenna supposed as wire antenna operating at 900 MHz and 1800 MHz can be modeled in HFSS as two cylinders separated by a small gap. The proposed antenna consists of a two cylinder radiating with a rectangular lumped port excitation between each arm of dipole to provide an radio frequency excitation to antenna element. The model is then covered by a vacuum box to permit radiation of fields, radiating boundary condition will be exercised to outer surface to work as infinite free space. Further the faces of the vacuum box are individually separate and distinct selected for assigning the radiation boundary. After the simulation the measured and simulated characteristics of the antenna are shown and drawn which used a numerical and experimental results regarding the radiation characteristics are presented and discussed. The return loss, VSWR, Directivity, gain, radiation pattern are evaluated. The figure illustrated the aims of this work, Also this model shows the comparison of smith chart for input impedance and polar plot for input impedance for the proposed antennas.
