The Investigation of PIN Diode Switch on Reconfigurable Antenna

Radioengineering - September 2017, Volume 26, Number 3 [DOI: 10… The antenna design is simulated on CSTMWS. The proposed antenna exhibits VSWR <2 and appreciable radiation patterns with positive gain over desired frequency bands. Microsoft Word - str_0429-0435

Frequency-reconfigurable antennas allow frequency hopping and dynamic spectrum allocation [1], while pattern-reconfigurableIn [13], the reconfigurable antenna can switch their operation between a patch broadside pattern and a monopole omnidirectional pattern using PIN diodes.

A NOVEL FREQUENCY RECONFIGURABLE SLOT ANTENNA - IJAET A novel multi frequency reconfigurable slot antenna has been presented. The proposed antenna is capable to reconfigure at eight different frequencies of 7.34-7.96 GHz by using three PIN diodes that are built into the ground plane slot .The slot antenna has nearly omnidirectional radiation pattern in A Reconfigurable Microstrip Patch Antenna with Frequency ...
