The wireless communication system has become very popular and has been developed rapidly over last one and a half decade. Wireless devices that operate in multiband frequencies, with smaller size, are now used by almost everyone. In this work, multiband dipole antenna with harmonic suppression capability has been designed. The Triple-band dipole antenna has been vigorous since it is simple, easy to be designed and fabricated. However, higher order modes (HOM) in these multiband antennas gives problems when designing such type of antennas. The proposed antenna consists of two designs; the first design is triple band dipole antenna with harmonic suppression capability which generate four frequency bands 0.8 GHz/2.4 GHz/ 4 GHz/ 5.8 GHz; The unwanted frequency of 4 GHz have been suppressed by adding single stub. The second design is dual band dipole antenna with two stubs to eliminate the unwanted frequency. Design two is repeated of three different scenarios 0.8/ 2.4 GHz, 0.8/ 5.8 GHz, and 2.4/ 5.8 GHz. The proposed concept has been investigated through simulation in CST Microwave studio and actual experimental works. The simulation and experimental results confirm the validity of the proposed antenna. There have been matching agreements between both simulation and measurements results.
