dc.description.abstractIn this thesis two antenna configurations are designed and modified, to operate in the 2.45 GHz ISM Band, to be used in body centric wireless communication applications. The two configurations were a Capacitively-Fed Folded Slot Antenna and a Rectangular Patch Antenna. The rectangular patch was modified to work as a quarter wavelength structure with three loading slots, and by adding a parasitic patch. This new modified configuration represents a contribution for this work. After the modifications, a bandwidth of 100 MHz and gain of 4.5dB were achieved. The capacitively-fed folded slot antenna was modified by adding eight loading slots which represents another contribution of this work. With this modification the antenna length was reduced to 16 mm in a 40 mm by 40 mm ground plane with a gain of 4.27 dB, and bandwidth of 20 MHz. Both antennas were fabricated and measured in the UPRM Microwave and Millimeter-Wave System Laboratory to validate the results obtained from simulations The effect of the human body was analyzed by simulations with a uniform model of the human body developed during the research. The human body does not show a significant effect in antenna performance. This effect was seen in both of the proposed antennas.en_US
dc.description.abstractEn esta tesis una antena de ranura plegada alimentada por acople capacitivo y una antena de parche rectangular, son diseñadas y modificadas, con el fin de ser utilizadas para aplicaciones de comunicaciones inalámbricas centradas en el cuerpo en la banda ISM de 2.45 GHz. El parche rectangular fue modificado para operar como una estructura de un cuarto de largo de onda con tres ranuras de carga, y añadiendo un parche parasítico, lo que representa una de las contribuciones de este trabajo. Con las modificaciones se logró cumplir con un ancho de banda de 100 MHz, y una ganancia de 4.5 dB. En el caso de la antena de ranura plegada, se modificó añadiendo ocho ranuras de carga, lo que representa la segunda contribución de este trabajo. La modificación realizada a esta antena logró reducir su largo a 16 mm en un plano de tierra de 40 mm por 40 mm con un ancho de banda de 20 MHz y una ganancia de 4.27 dB. El efecto del cuerpo humano fue estudiado mediante simulaciones utilizando un modelo uniforme del cuerpo humano desarrollado durante la investigación. El cuerpo humano reflejo un efecto no significativo en el comportamiento de la antena. Dicho efecto se observó en las dos antenas.en_US
