摘要：

A new, circularly polarized small-size microstrip antenna using a proximity coupled feed method is proposed, A simple configuration based on a cross slot with unequal slot lengths on a circular patch is adopted to realize a small-size element antenna, The proposed antenna has no 90 degrees hybrid coupler for circular polarization, The measured results verify the circular polarization, and the antenna radius was reduced by about 36% by using the slot lengths which are nearly equal to the diameter of the circular patch antenna, Good impedance and axial ratio characteristics have been obtained.
