Dual frequency Microstrip Antenna design for 700 MHz UHF Band and Wlan Application

Recently Terrestrial Digital Television, TDT, has been implemented in Mexico, as a consequence, the 700 MHZ UHF Band has been opened to new telecommunications services, particularly wireless mobile communication. This technological advance means an antenna design challenge due to it is necessary to design a dual frequency antenna which dimensions must be enough small, satisfy gain, resonance frequency, impedance, wideband requirements, and low cost, in that sense, this work describes the simulation, design and implementation of Microstrip Antenna for 700 MHZ UHF Band (698-806 MHz) and for Wireless Lan Application, (2400-2483.5 GHz Wi Fi ISM) to be used on radio mobile devices.
