Abstract :
A previous study has shown that circular polarisation reduces multipath delay spread in indoor radio systems. However, the effect is more difficult to measure in outdoor fixed wireless access (FWA) systems. Presented is a switchable-polarisation antenna that enables accurate comparison of linear against circular polarisation in outdoor measurements. Results show that circular polarisation reduces the multipath delay spread in suburban FWA systems at 3.5 GHz.
