Abstract

PURPOSE: A non-directional antenna is provided to allow the communication with the satellite on the moving environment and to improve the sensitivity and to be used as a relay antenna having minimization, high sensitivity, easy installation, and light weight characteristics. CONSTITUTION: The non-directional antenna comprises a plurality of microstrip patch array antennas(B) arrayed within a semicircle frame(A), a plurality of LANs(C) connected to each microstrip patch array antenna, a cable(D), a pad(E), a reflecting surface(F), and a transmission/receiving cable(G). All microstrip patch array antennas are placed to give their own directivity, where one antenna is directional to the target and the others are slightly different directivity. Thus one antenna receives a wave and the gain at this antenna is highest and the gains of other antennas are decreased. The gains less than the highest gain are amplified. This antenna receives any directional wave when it is mounted on the moving car.
