An efficient multiband antenna for satellite and 4G communication systems

In this paper, an efficient and compact multi-band micro strip patch antenna for both the 4G WiMAX (3.4GHz) and for satellite applications (4.9GHz) is developed. The three resonant modes of the proposed antenna are 3.4 GHz, 4.4 GHz, 4.9 GHz. By proper adjustment of the U shaped slotted patch antenna enables the operation of multi band with a -10dB return loss, a omni directional radiation pattern and a good antenna gain with high efficiency. Design simulation and optimization processes are carried out with the aid of the Advanced Design System (ADS) electromagnetic simulator that uses the full-wave Method of Moment (MoM) numerical technique [3]. The losses that are caused by both the substrate and metallization are taken into account during the simulation process. Antenna compactness was our target during the design process to fix the antenna in the new 4G communication mobile equipments. The proposed antenna is suitable for wireless communication applications requiring a small antenna.
