C-shaped, E-shaped and U-slotted patch antennas: Size, bandwidth and cross-polarization characterizations

A class of slotted antenna topologies have been compared with respect to their size, RF-performance and radiation properties. It has been shown that position and orientation of slots in these antennas can alter their properties in different ways. Comparison of these antenna topologies reveals that C-shaped and double C-shaped patch antennas are compact, narrow band antennas with relatively high cross-pol. The U-slotted and E-shaped patch antennas have been shown to have wide-band response with relatively large size.
