A
wireless access gateway for communication of wave signals at radio frequencies within a
frequency band, includes an access gateway enclosed in a housing including a bottom wall and a main circuit board overlying the bottom wall and having an upper surface substantially parallel to the bottom wall. The gateway is equipped with an antenna
system including at least two antennas: a first linearly polarized antenna for propagating a first wave
signal along a first polarization axis including a first
radiating element extending along a first longitudinal axis
lying on a first plane substantially parallel to the
base plane, and a second linearly polarized antenna for propagating a second wave
signal along a second polarization axis oriented perpendicularly to the first polarization axis, the second antenna including a second
radiating element extending along a second longitudinal axis
lying on a second plane oriented perpendicularly to the first plane. The first and second antennas are positioned relative to each other at a distance of at least λ / 2, where λ is the
wavelength corresponding to a
radio frequency within the
frequency band.
