Loop-Type Antenna and Antenna Array

摘要

A loop-type antenna for radio frequency identification includes a main body and a feed portion. The main body includes a loop member and at least one pair of coupled sections. The loop member has at least one gap. Each of the coupled sections is connected with one end of corresponding one of the at least one gap. The pair has identical extension direction. The feed portion is electrically connected with the loop member in the manner that the loop member is symmetrical in terms of the feed portion. An antenna array for radio frequency identification also is provided.
