abstract

  • A class of popular linearly polarized slotted antennas are compared with respect to their RF mechanism, radiation mechanism, impedance matching, and cross polarization characteristics for wireless communication frequency band 1.9-2.4 GHz.It is found that C-shaped and double C-shaped patch antennas, even though miniaturized, suffer from narrow bandwidth and high cross polarization level, due to its orientation of slot. U-slotted and E-shaped patch antennas show high bandwidth with minor penalty in size and cross polarization level. In order to understand the effect of slot on the radiation in these antennas, a novel strategy of looking at the near-field of these antennas has been presented. These near-field plots are analyzed to explain certain far-field radiation characteristics in these antennas such as- cross-pol level. © 2012 Wiley Periodicals, Inc.
