In this research, we developed a dual antenna array for the household reception of openly
analogical television (TV) frequencies. This array was designed on Flame Retardant-4 (FR-4)
as substrate, in order to obtain a low cost prototype.
The interest in this area is because of the fact that the openly TV is one of the most important
communication media in our country. From information supplied in 2009 in the National
Survey over availability and use of Technologies, it reveals that the 72.8% of the population
uses the services of the openly TV (Instituto Nacional de Estadística, Geografía e Informática
[INEGI], 2009). A TV can be found in almost all homes of the country, but only 13.6%
correspond to digital technology, while only a half of homes with a digital TV requires
signal payment. The availability of TVs in Mexican homes in 2010 remained without severe
changes (INEGI, 2010).
