## Abstract

An apparatus providing a direct chip to waveguide transition, comprising: one or more waveguides, a chip partially embedding each of the waveguides at a transition area positioned at a narrow side of each waveguide, and a transmitting element disposed at each of the transition areas, thereby providing one or more simultaneous, direct transitions between the chip and the waveguides.

## Claims

### Claim 1

An apparatus providing a direct chip to waveguide transition, comprising:
multiple waveguides;
a chip partially embedding two or more of said multiple waveguides along each of one or more edges of the chip, each of said multiple waveguides partially embedded by a respective transition area positioned at a narrow side of each waveguide where the narrow side runs perpendicular to the chip, and
a respective transmitting element disposed at an embedded portion of the corresponding transition area in each of the multiple waveguides, each transmitting element comprising a respective antenna, the antennas collectively providing multiple simultaneous, direct transitions between said chip and said multiple waveguides.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein a thinned periphery of said chip comprises at least a portion of each of said transition areas.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein a thickness of said thinned periphery of said chip is approximately 200 microns.

### Claim 4 (depends on 2)

The apparatus of claim 2, wherein each said antenna is a ring antenna that is disposed at said thinned periphery of said chip.

### Claim 5 (depends on 2)

The apparatus of claim 2, wherein said respective transmitting element comprises a corresponding tapered slot passage providing wideband signal transmission capability.

### Claim 6 (depends on 5)

The apparatus of claim 5, wherein a substrate layer is electrically connected to said thinned periphery of said chip, and galvanically connected to a respective one of said multiple waveguides of the corresponding transition areas.

### Claim 7 (depends on 6)

The apparatus of claim 6, wherein said respective tapered slot passage comprises a first portion disposed at said thinned periphery of said chip, and a second portion disposed at said substrate layer.

### Claim 8 (depends on 7)

The apparatus of claim 7, wherein a size of said chip is in an order of 6 mm ×6 mm.

### Claim 9 (depends on 7)

The apparatus of claim 7, wherein a combined size of said chip and said substrate layer is 16 mm ×16 mm.

### Claim 10 (depends on 7)

The apparatus of claim 7, wherein said chip is configured to operate at frequencies of approximately 100 GHz.

### Claim 11 (depends on 1)

The apparatus of claim 1, wherein said narrow side of each of said multiple waveguides is 0.8 mm.

### Claim 12 (depends on 1)

The apparatus of claim 1, further comprising a balun configured to balance a signal between each said transmitting element and a corresponding drive circuit of said chip.

### Claim 13 (depends on 1)

The apparatus of claim 1, further comprising a respective tuning element configured with said corresponding said transmitting element to adjust a frequency response of said respective transmitting element to suit a signal transmitted via a corresponding one of said multiple waveguides.
