Abstract
In this article, we present a new broadband CP square-slot antenna with an inverted F-shaped feed-line. The antenna is composed of an inverted F-shaped feed-line, pairs of isosceles triangular chamfers, I-shaped slots, rectangular slots and triangular patches, and a Z-shaped strip. By introducing these strips and slots into the square-slot, multiple CP modes can be stimulated simultaneously, which eventually enhances 3-dB ARBW and 10-dB impedance bandwidth (IBW) of the presented antenna. The measured results show that its IBW (|S11| < −10 dB) is about 7.2 GHz (87.8% from 4.6 to 11.8 GHz) and its ARBW (AR < 3 dB) is 8.3 GHz (96% from 4.5 to 12.8 GHz).
