A comparative analysis of various reconfigurable and multiband antenna concepts is presented. In order to satisfy the requirements for the advanced systems used in modern wireless and radar applications, different multiband and reconfigurable antennas have been proposed and investigated in the past years. In this paper, these design concepts have been classified into three basic approaches ... Reconfigurable Wide Bandwidth Using Novel Extraction ... The entire approach is folded into four different designs. The first design proposes a monopole antenna where asymmetric flower type corners and mushroom shape encloses by T-slot is cut on the patch. This new shaped antenna covers wide impedance bandwidth of about 14.5 GHz within range from 21.5 to 36 GHz. (PDF) Design of reconfigurable slot antennas

For a non-reconfigurable design, these may be hard-wired slotline short circuits, but in the reconfigurable design, they are implemented with pin diodes. The short in the slot results in a reformation of the electric field distribution along the slot leading to a shift of the null in the short direction. The
