Abstract :
The effect of curvature on the characteristics of a rectangular patch antenna is studied theoretically and experimentally. For the TM01 mode it is found that the resonant frequency is not affected by curvature. However, as curvature increases the pattern broadens, the resonant resistance decreases, the Q-factor is smaller and the bandwidth is larger. Good agreement between theory and experiment is obtained.
