Dual band dipole antenna with harmonic suppression capability
… In this work, multiband dipole antenna with harmonic suppression capability has been designed. The dual-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 …

Triple band dipole antenna with harmonic suppression capability
… 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 …

Dual band monopole antenna with harmonic suppression capability
… different dual band antennas also suffer from harmonic generation and higher order resonances. Due to these higher order resonances electromagnetic interference and noise increases and thus they bring down the performance of communication systems. In order to address the problem this research …

Miniaturised and reconfigurable planar filters for ultra-wideband applications
… edges and a single zero in the stop band for harmonic suppression is discussed in the second section. Moreover, the development of notched rejection bands are studied and several novel methods to create a single and multiple notched bands employing the square ring shape structure are proposed. …
