THE CONFORMAL ANTENNA STRUCTURE FOR A IMPROVING INPUT IMPEDANCE

摘要

PURPOSE: A conformal antenna structure for increasing input impedance is provided to replace a frame of an aircraft with a radome and increase the input impedance of a conformal antenna which prints an antenna on the radome, thereby facilitating antenna matching. CONSTITUTION: An antenna insertion space unit is covered by a radome(21) along with the surface of the frame in which an antenna is formed. An antenna power supply unit(40) is connected to an antenna radiating unit which is printed on the radome by the bottom of the antenna insertion space unit. A monopole antenna(31) and a dipole antenna(32) are connected to the antenna power supply unit. The dipole antenna has a bent shape to surround a monopole antenna. The dipole antenna has an induction coupling structure with the monopole antenna.
