A bandwidth reconfigurable antenna for devices in low UWB-applications

Band notched
E-shaped slot
PIN diode
Switchable frequency
Ultra-wideband

A reconfigurable simple design planar antenna for ultra-wideband
applications is proposed, with E-shaped slot contained four narrow vertical
slots that has the capacity of switching using four PIN diodes with a ground
plan and a microstrip power line. An additional circularly polarized (CP)
band is obtained by changing the on/off states of the PIN diodes. Moreover,
the four PIN diodes are attached in the middle of the E-shape slot and used
to switch the radiation flow of the patch. For validation, a patch antenna
design is offered, based on a distinctive situation analysis. The antenna offers
the low-ultra-wideband (UWB) frequencies band. Therefore, the switch of the
operating states of PIN diodes gives us a good bandwidth re-configurability.
In addition, with this flexible configuration we achieve a good -10 dB
bandwidths with the ability to change the bandwith ranges from narrow-band
2.3 GHz to wide-band 3.1 GHz. Also, we achieve a large band for 3 dB AR
is 2.57 GHz.
