<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT This work proposes to analyze changes in the resonance frequencies of patch antenna induced by a slot on the radiant coat, where to find a clear relationship between changes in resonance frequency due to the position and orientation of the slot is the objective. We used a numerical software based on Finite Element method in order to simulate parametric sweeps of slot geometry, then it allowed us to identify a pattern of change in the response of the coefficient of reflection (S11) of the antenna. The results showed that variations in the fundamental resonance frequency and the resonance of higher-order modes depend on the orientation and position of the slot. The relationship between the resonance frequencies and the position and orientation of the slot was described by means of mathematical models, which allow to tune frequencies by means of geometric parameters of the slot such orientation and position. Also, it established that the modes of resonance (TM*) are affected according to the orientation of the slot. In addition, it is an alternative to multi-band patch antennas design.]]></p></abstract>
