ANTENNA FOR A WIRELESS TERMINAL

摘要

PURPOSE: An antenna for a wireless terminal is provided to obtain a high gain by using a dielectric body such as a ceramic. CONSTITUTION: An antenna for a wireless terminal comprises a cylindrical outer conductive body(21), a cylindrical inner conductive body(22), a cylindrical inner dielectric body(23), an inner conductive body(22) of a concentric cable, an outer conductive body(25) of a concentric cable, an inner dielectric body(26) of a concentric cable, an impedance matching dielectric body(27). The cylindrical inner dielectric body(23) has a first dielectric constant. The inner dielectric body(26) has a second dielectric constant. The impedance matching dielectric body(27) has a third dielectric constant.
