Performance Measurement of Polarization Diversity Printed Dipole Antenna Using High Frequency Pin Diode for WLAN
In this paper, polarization diversity antenna system is implemented to achieve the vertical and horizontal polarization by using two orthogonally placed printed dipole antennas for ISM band applications. Simulation, fabrication and measurements are carried out for polarization diversity printed dipole antenna at 2.4GHz center frequency. Here, two orthogonal printed dipoles are simulated in HFSS simulation software and are fed by using via balun structure. A pin diode (HSMP 1321) is used to switch between vertical and horizontal polarization for the respective antenna and the specified polarization is achieved.
