Abstract

An antenna assembly is provided. The antenna assembly includes a ceramic carrier having a first surface and a second surface, the second surface being opposite the first surface. The antenna assembly further includes an antenna pattern. The antenna pattern includes a first antenna portion positioned at least partially on the first surface of the ceramic carrier. The antenna pattern further includes a second antenna portion comprising a plurality of conductive vias extending through the ceramic carrier from the first antenna portion to the second surface of the ceramic carrier.

First claim

What is claimed is:

1 . An antenna assembly, comprising:
a ceramic carrier having a first surface and a second surface, the second surface being opposite the first surface; an antenna pattern, comprising:
a first antenna portion positioned at least partially on the first surface of the ceramic carrier; and
a second antenna portion comprising a plurality of conductive vias extending through the ceramic carrier from the first antenna portion to the second surface of the ceramic carrier;
wherein the plurality of conductive vias is located along a first sidewall of the ceramic carrier, the first sidewall being greater in length than adjacent sidewalls of the ceramic carrier.

2 . The antenna assembly of claim 1 , wherein the plurality of conductive vias is positioned along a sidewall of the ceramic carrier, each conductive via of the plurality of conductive vias being located a distance from the sidewall.

3 . The antenna assembly of claim 1 , wherein the antenna pattern further comprises:
a third antenna portion positioned on the second surface of the ceramic carrier, wherein the second antenna portion electrically couples the first antenna portion to the third antenna portion.

4 . The antenna assembly of claim 1 , wherein the antenna pattern further comprises:
a fourth antenna portion positioned on the second surface of the ceramic carrier; and a fifth antenna portion positioned on the second surface of the ceramic carrier, wherein the second antenna portion electrically couples the first antenna portion to the fourth antenna portion, wherein the second antenna portion electrically couples the first antenna portion to the fifth antenna portion.

5 . The antenna assembly of claim 1 , wherein the antenna assembly comprises a GPS antenna.

6 . The antenna assembly of claim 5 , wherein the GPS antenna operates at an L1 frequency band.

7 . The antenna assembly of claim 6 , wherein the antenna assembly has a return loss in a range of about −12 dB to about −16 dB.

8 . The antenna assembly of claim 6 , wherein the antenna assembly has a band width in a range of about 80 MHz to about 85 MHz.

9 . The antenna assembly of claim 6 , wherein the antenna assembly has a radiation efficiency in a range of about −0.30 to about −0.40.

10 . The antenna assembly of claim 5 , wherein the GPS antenna operates at an L5 frequency band.

11 . The antenna assembly of claim 10 , wherein the antenna assembly has a return loss in a range of about −25 dB to about −30 dB.

12 . The antenna assembly of claim 10 , wherein the antenna assembly has a band width in a range of about 130 MHz to about 135 MHz.

13 . The antenna assembly of claim 10 , wherein the antenna assembly has a radiation efficiency in a range of about −0.20 to about −0.30.

14 . The antenna assembly of claim 1 , further comprising:
a circuit board, wherein the circuit board is coupled to the second surface of the ceramic carrier.

15 . The antenna assembly of claim 1 , wherein the antenna assembly does not include a metal sidewall.

16 . A communication device, comprising:
an antenna, comprising:
a first antenna portion positioned at least partially on a first surface of a ceramic carrier; and
a second antenna portion comprising a plurality of conductive vias extending through the ceramic carrier from the first antenna portion to a second surface of the ceramic carrier,
wherein the second surface of the ceramic carrier is opposite the first surface of the ceramic carrier and the plurality of conductive vias is located along a first sidewall of the ceramic carrier, the first sidewall being greater in length than adjacent sidewalls of the ceramic carrier.

17 . The communication device of claim 16 , wherein the plurality of conductive vias is positioned along a sidewall of the ceramic carrier, each conductive via of the plurality of conductive vias being located a distance from the sidewall.

18 . The communication device of claim 16 , wherein the antenna further comprises:
a third antenna portion positioned on the second surface of the ceramic carrier, wherein the second antenna portion electrically couples the first antenna portion to the third antenna portion.

19 . The communication device of claim 16 , wherein the antenna further comprises:
a fourth antenna portion positioned on the second surface of the ceramic carrier; and a fifth antenna portion positioned on the second surface of the ceramic carrier, wherein the second antenna portion electrically couples the first antenna portion to the fourth antenna portion, wherein the second antenna portion electrically couples the first antenna portion to the fifth antenna portion.
