High-Frequency Antenna Array

View page
US Patent:
6885344, Apr 26, 2005
Filed:
Apr 25, 2003
Appl. No.:
10/423303
Inventors:
Farrokh Mohamadi - Irvine CA, US
International Classification:
H01Q001/38
US Classification:
343700MS, 343767
Abstract:
A patch antenna is excited by a linear feedline through a cross-shaped aperture in a shield layer. The cross-shaped aperture includes a longitudinal arm running parallel to the linear feedline and a transverse arm running orthogonally to the longitudinal arm.

Inductively-Coupled Antenna Array

US Patent:
6963307, Nov 8, 2005
Filed:
Apr 25, 2003
Appl. No.:
10/423129
Inventors:
Farrokh Mohamadi - Irvine CA, US
International Classification:
H01Q001/38
US Classification:
343700MS, 343856, 343893, 342372
Abstract:
An antenna array comprises a plurality of integrated antenna units. Each integrated antenna unit includes an oscillator coupled through a transformer to an antenna. The oscillators are formed on a semiconductor substrate and the antennas and transformers are formed in metal layers overlaying the semiconductor substrate.

Phase Management For Beam-Forming Applications

View page
US Patent:
6982670, Jan 3, 2006
Filed:
Jun 3, 2004
Appl. No.:
10/860526
Inventors:
Farrokh Mohamadi - Irvine CA, US
International Classification:
H01Q 3/24
US Classification:
342372, 342373
Abstract:
A beam-forming antenna system includes an array of integrated antenna circuits. Each integrated antenna circuit includes an oscillator coupled to an antenna. A network couples to the integrated antenna units to provide phasing information to the oscillators. A controller controls the phasing information provided by the network to the oscillators. In an alternative embodiment, the phasing to each antenna element is controlled through a fixed corporate feed network. The relative gains of the antenna signals received or transmitted through the fixed corporate feed may be adjusted with respect to each other to provide a beam steering capability.

Beacon-On-Demand Radar Transponder

View page
US Patent:
7042388, May 9, 2006
Filed:
Jul 14, 2004
Appl. No.:
10/891352
Inventors:
Farrokh Mohamadi - Irvine CA, US
International Classification:
G01S 13/08
G01S 13/74
G01S 13/78
US Classification:
342 51, 342 30, 342 45
Abstract:
A radar transponder is provided that synchronizes the encoding of repeated radar pulses using an envelope detector to detect the envelope of received radar pulse signals. An edge detector detects the pulse edges in the envelope so that code words may be multiplied with the received radar pulse signals synchronously with the detected pulse edges to provide an encoded pulse train that may be transmitted to a radar interrogator.

Beam Forming Phased Array System In A Transparent Substrate

View page
US Patent:
7126541, Oct 24, 2006
Filed:
Feb 2, 2005
Appl. No.:
11/049098
Inventors:
Farrokh Mohamadi - Irvine CA, US
International Classification:
H01Q 1/38
US Classification:
343700MS
Abstract:
In one embodiment, an antenna array is provided that includes a transparent substrate, a plurality of antennas formed on a surface of the transparent substrate, and an integrated circuit, the integrated circuit including an RF beam forming interface circuit adapted to perform at least one of phase-shifting and attenuating an RF signal according to a transmit beam forming command to form an RF driving signal for driving the plurality of antennas, the RF beam forming interface circuit also adapted to perform at least one of phase-shifting and attenuating a received RF signal from the plurality of antennas according to a receive beam forming command.

US Patent:
7126542, Oct 24, 2006
Filed:
Mar 7, 2005
Appl. No.:
11/074027
Inventors:
Farrokh Mohamadi - Irvine CA, US
International Classification:
H01Q 1/38
US Classification:
343700MS
Abstract:
In one embodiment, an antenna array is provided that includes a semiconductor substrate having a first surface and an opposing second surface; a plurality of heavily-doped contact regions extending from the first surface to the second surface; a plurality of antennas formed on an insulating layer adjacent the first surface, each antenna being coupled to corresponding ones of the contact regions by vias; driving circuitry formed on the second surface of the substrate, wherein the driving circuitry is configured such that each antenna corresponds to an RF beam forming interface circuit adapted to perform at least one of phase-shifting and attenuating an RF signal according to a transmit beam forming command to form an RF driving signal for driving the corresponding antenna, the RF beam forming interface circuit also adapted to perform at least one of phase-shifting and attenuating a received RF signal from the corresponding antenna according to a receive beam forming command, and a waveguide network formed in a network substrate adjacent the second surface, wherein the waveguide network is adapted to provide the RF signal to and to receive the received RF signal from each RF beam forming interface circuit.
