The proposed work focuses on the experimental investigation of radiation characteristics of the discarded IC chips mounted on the dielectric substrate when fed trough one of the metal leg pins. Several sets of the experimental results are obtained using Vector Network Analyzer to obtain the return loss characteristics of the proposed structure. The return loss characteristics reveal that at some frequencies the ICs certainly show radiation mechanism. Feeding the same chip at different pin locations, changes the resonant frequency. The measured radiation pattern of the IC chip shows an omni-directional characteristic. This experimental study also reveals that the ICs can be easily interfered by the surrounding radiation prevalent in any wireless environment following the reciprocity principle of an antenna.
