Abstract

PURPOSE: A microstrip patch array antenna for transmitting and receiving high-frequency signal is provided to reduce the manufacturing cost of an antenna by producing an antenna for Ku-band signal in a plane type using a printed board. CONSTITUTION: A circuit is designed by using a dielectric printed board having a dielectric constant of below 3. Patch elements are connected through strip lines to increase the transmitting/receiving sensitivity. The strip lines are determined according to the dielectric constant and thickness of the printed board. The size and spacing of the patch elements are determined according to the wavelength of a predetermined frequency, so that a signal of Ku-band(10GHz-12GHz) is received by an antenna employing the patch elements. The length and thickness of a feed line is determined by the dielectric constant of the printed board. The efficiency of antenna becomes 1.5 and the gain thereof is 30 dB(decibel) over.
