METHODS AND APPARATUS FOR REDUCING RADIO FREQUENCY INTERFERENCE FOR COLLOCATED ANTENNAS |
摘要 |
<p>Methods and apparatus for a plate to prevent energy from a first antenna from interfering with a collocated second antenna. In one embodiment, the plate includes first and second conductive layers to shadow the second antenna and thereby block energy from reaching the second antenna. A resonant quarter wavelength spacing of the plates forces energy broadside minimizing the spillover the edge caused by diffraction. Multiple conductive layers having increasing radii can block diffracted energy from spilling over and around the plate. The multiple plates of increasing radii affect a waterfall-like spill wherein energy is lost in each level.</p> |
