Abstract :
In this paper, small slot antennas with low cross polarization are investigated. We employ a symmetrical meander slot structure to design a reduced size slot antenna fed by a microstrip line. It acts as a multiple-folded slot loop antenna with an area reduction up to 50%, while the cross-polarization less than -30 dB can be achieved. The analysis and design of the antennas are accomplished using a commercial full wave simulation software The results compare quite well with the experiments.
