Abstract :
A new microstrip dual-band polarization reconfigurable antenna is presented for WLANs operating at 2.4 GHz and 5.8 GHz The antenna consists of a square microstrip patch that is aperture coupled to a microstrip line located along the diagonal line of the patch. The dual-band operation is realized by employing the TM10 and TM30 modes of the patch antenna. Four shorting posts are inserted into the patch to adjust the frequency ratio of the two modes. The center of each edge of the patch is connected to ground via a PIN diode for polarization switching. By switching between the different states of PIN diodes, the proposed antenna can have horizontal, vertical, or 45° linear polarizations for the two frequency bands.
