In this paper, a miniaturized quarter-wavelength rectangular patch antenna with coaxial feed is proposed. The resonance frequency of the proposed antenna is simulated and measured so that the relationship between its mechanical deformation and resonance frequency can be determined. Also, additional tensile tests are employed to further clarify the relationship by increasing strain increments per loading...
Wireless sensors on the outer surface of aircrafts are of interest for both research and control of modern aircrafts. However, the constraints are quite challenging for the antenna design: Since the surface may be conductive and the constructive height of the sensor must remain low, e.g. below one millimeter, the antenna gain and directivity can be quite unfavorable. Moreover, the reliability of the...
