Abstract:
In some wireless applications, such as Radio Frequency IDentification (RFID), printed antennas are attached to non-flat surfaces or flexible substrates such as paper or soft plastics. This might cause distortion to the communication system because of unwanted bending of the antenna structure. Previous work has shown that bending of traditional half wavelength dipole antennas with thin conductors can significantly reduce the operating range of a passive RFID system. In this paper we investigate if printed dipoles with wide conductive strips is less sensitive to this kind of distortion. Computer simulations and verifying measurements are used to study the effects of dipole bending. Results show that a carefully designed printed dipole can be a good choice for applications where distortion due to bending of antenna structures might occur.
