The antenna performance of three 2×2 802.11n wireless routers is assessed at 2.4GHz using a laptop as a reference client. The analysis combines in-situ measured 3D radiation patterns with state-of-the-art 3D ray-tracing for a number of different client locations and access-point/client orientations in a typical three-floor home. A router employing two PIFAs achieves the highest average signal level on the top floors (3-10dB better); a router with two external dipoles on the same floor level (1-5dB better); and a router with two patches is in-between and results in the largest signal variations (5-15dB larger dynamic range).
With accompanying conference poster.
The antenna pattern measurements used the extensive laboratory facilities and the anechoic chamber at the Centre for Communications Research, University of Bristol, UK. Evangelos Mellios would like to thank the University of Bristol Centenary scheme for his postgraduate scholarship.
