摘要

A microstrip patch antenna fed with two opposing microstrip lines is designed. The antenna has four cuts in its corners in order to introduce PIN diode to have a polarization agile antenna by changing the diodes states. Two vertical slots inside the patch are created for axial ratio and bandwidth enhancement. A separate DC biasing is inserted for proper operation of the diodes. Some antenna characteristics such as reflection coefficient, axial ratio, radiation pattern and gain are investigated and optimized through several parametric studies of the antenna geometry. This type of antenna is widely preferred in wireless communication systems.
