Summary:
To reduce a risk of damage from an exposure and the guarantee of a stable receive level, in case of the system of a wireless LAN, a printed type inverted F antenna for beamsteering is designed and its characteristic is measured. A parasitic element having the optimized length and interval is attached in both sides of the printed type inverted F antenna for beam-steering. As a result of it, the first, when the antenna has a beamsteering to the front area, it obtained the vertical polarization gain of -1.02dBd, the ratio of the front and the back of 17.48dB. The second, when it has a beam-steering to the back, it obtained the vertical polarization gain of -1.66dBd, the ratio of the front and back of 17.03dB. The last, when it has no beam-steering, it maintains the original characteristic of the printed type inverted F antenna for beam-steering, and is appropriate for a antenna of a radio intelligence by having a horizontal polarization.
