His work is particularly relevant in the realms of vehicle-mounted antennas and satellite communication systems.

Latest Patents

One of Asim Ghalib's latest patents focuses on the "Radio cross-section reduction of conformal antennas mounted on vehicles." This invention aims to reduce the radar cross-section (RCS) of a vehicle/antenna combination by utilizing an antenna and ground plane of substantially the same area. The design incorporates a frequency selective surface (FSS) that is transparent to out-of-band frequencies while reflecting one or more operating frequencies of the antenna. Additionally, a multilayer absorber beneath the FSS captures out-of-band frequencies that a larger ground plane might otherwise reflect back to the vehicle body.

Another notable patent is for "Dual-band (S and C) sub-reflectors for frequency-reuse types of satellite communication systems for commercial and defense applications." This invention features subreflectors that cover the S and C bands, designed as a three-dimensional waveguide with cross dipoles on each end. Each dipole branch is electrically connected by a conductor that runs through the center of a substrate filling the waveguide's volume. The frequency selective surface sub-reflector allows the S-band antenna to transmit with an insertion loss of less than 0.5 decibels while reflecting C-band transmissions with losses under 15 decibels.
