Claims

[Claims for Utility Model Registration] 1. A microstrip planar antenna in which power is supplied by a feeding system in which a plurality of sub-array antennas are arranged in a matrix and each sub-array antenna is connected in a tournament manner, A microstrip planar antenna characterized in that a power divider with a power distribution ratio of n:m is disposed at a branch point of the system. 2. A subarray block is composed of four subarray antennas arranged in a 2×2 array and three power dividers provided in the feed system that connects each subarray antenna, and a plurality of these subarray blocks are used to form a matrix. 2. A microstrip planar antenna according to claim 1, which is a registered utility model and is constructed by arranging subarray blocks in a tournament manner and connecting each subarray block in a tournament manner through a power supply system.
