Abstract.
In this paper reports a cylindrical rectangular antenna for wireless
communications. Omnidirectional antennas are those that radiate the signal in
all directions, however, much of the radiated signal is not used. The directive
antennas are those whose property radiate and receive electromagnetic waves
with better efficiency in algunas ,directions. This paper presents a cylindrical
rectangular antenna, which aims to get better signal use and show an increase in
the coverage area. To obtain the results, simulations and analysis of the
structure under study HFSS ™ (High Frequency Structural Simulator) was
used. The level of signal, channel, frequency and MAC (Media Access Control)
address was made through the Xirrus Wi -Fi Inspector program.To measure the
rate of transmission sites were used: http://speedtest.copel.net/. The results
showed a good response on the signal level and the speed of transmission,
compared to an existing market.

Introduction
Second Balanis, the antenna is a metallic device used for radiation or reception of
radio waves [1]. The directional antennas are those that have the property to radiate or
receive electromagnetic waves with better efficiency in some directions and the omni-
directional antennas are those that have a diagram non-directional. Due to the low
utilization of the signal propagated by omnidirectional antennas, it was thought a
rectangular cylindrical antenna, directive, for better utilization of signal received and
propagated [2]. The antenna uses, as substrate, Ultralam ® 3850, from Rogers
Corporation. For the achievement of results, simulations and analysis of the structure
in study used the program HFSS® (High Frequency Structural Simulator).

Theory
The calculations of resonance frequency, length (2l) and width (w) were developed
through the program Fortran Power Station [3]. The antenna was modeled using the
