Latest Patents

One of his latest patents is the "Antenna performance evaluation method and apparatus." This invention focuses on rapidly testing phased array antennas for performance degradation using a beam steering computer unit and built-in test equipment. The design includes a plurality of bays in a planar matrix, each bay containing subarray modules with pairs of dipoles. The beam steering unit controls the scanning of driver cards that apply bias voltages to phase shifter diodes or bits of various fixed angular sizes in both the main array and subarray. The sequential testing of these bits for current faults provides critical information on the number, size, and location of failed bits, which helps determine performance degradation against a predetermined threshold. Notably, larger phase bits in the main array are given more weight than smaller subarray bits. The impact of these failures on sum beam gain and azimuth and elevation differences pattern null depths is computed and compared with the threshold to assess whether the performance is acceptable.

Another significant patent is the "Rod-excited waveguide slot antenna." This invention features a power-radiating slotted waveguide that includes one or more rods mounted inside the waveguide adjacent to a non-inclined slot. The rod facilitates power radiation while minimizing undesirable cross-polarized radiation due to the slot's design. The energy radiated from the slot can be adjusted by varying the area between the rod and the waveguide walls.
