  • Abstract
    The impedance of a simple open slot antenna was measured as a function of frequency and was then compared with the theoretical values obtained through Babinet´s principle from the known values of the admittance of its complementary antenna, the strip dipole. A careful experimental study was then made of the impedance of the same slot with several different cavity backings. The impedance was found both as a function of frequency and of the various parameters of the cavity, namely, the cross-sectional size of the cavity, the medium filling the cavity, and the type of termination of the cavity.
