Abstract

"ANTENA DE DUAS BANDAS". Sendo que a presente invenção descreve uma antena de duas bandas para um dispositivo portátil sem fio que pode ser adequadamente usado para um telefone celular e serviços de telefone de comunicação pessoal (PCS), melhorando uma estrutura de mola de uma antena helicoidal para obter duas bandas largas de 900 MHz de telefone celular e 1900 MHz do fone PCs. A antena de duas bandas para o dispositivo sem fio, no qual a antena helicoidal tem uma mola embutida, inclui: uma mola que consiste de uma mola inferior fixada a uma haste de metal da antena helicoidal a intervalos pré-determinados de mola para transmitir e receber uma freq³ência de 1900 MHz; e uma mola superior possuindo intervalos de mola mais estreitas do que a mola inferior, a mola superior e a mola inferior sendo capazes de transmitir e receber uma freq³ência de 900 MHZ."TWO BAND ANTENNA". The present invention describes a two-band antenna for a portable wireless device that can be suitably used for a cellular telephone and personal communication telephone (PCS) service, improving a coiled antenna spring structure to obtain two bands. 900 MHz wide cell phone and 1900 MHz handset PCs. The two-band wireless antenna in which the helical antenna has a built-in spring includes: a spring consisting of a lower spring attached to a metal of the coiled antenna at predetermined spring intervals to transmit and receive a frequency of 1900 MHz; and an upper spring having narrower spring intervals than the lower spring, upper spring and lower spring being capable of transmitting and receiving a frequency of 900 MHz.
