Abstract
An antenna assembly includes a first magnetic substrate having a first surface and a second surface opposite from the first surface. One or more antenna elements are disposed on the first surface of the first magnetic substrate. A microstrip feed line is disposed on the second surface of the first magnetic substrate. A second magnetic substrate is secured to the first magnetic substrate. The second magnetic substrate includes one or more cavities aligned with the one or more antenna elements and the microstrip feed line.

An antenna assembly comprising:
- a first magnetic substrate having a first surface and a second surface opposite from the first surface;
- one or more antenna elements disposed on the first surface of the first magnetic substrate;
- a microstrip feed line disposed on the second surface of the first magnetic substrate;
- a second magnetic substrate secured to the first magnetic substrate, wherein the second magnetic substrate comprises one or more cavities aligned with the one or more antenna elements and the microstrip feed line;
- a ground plane connected to the second magnetic substrate, wherein the one or more cavities are disposed between the one or more antenna elements and the ground plane.
A method of forming an antenna assembly, the method comprising:
- disposing one or more antenna elements on a first surface of a first magnetic substrate;
- disposing a microstrip feed line on a second surface of the first magnetic substrate, wherein the second surface is opposite from the first surface;
- forming one or more cavities in a second magnetic substrate;
- securing the second magnetic substrate to the first magnetic substrate, wherein said securing comprises aligning the one or more cavities with the one or more antenna elements and the microstrip feed line;
- and
- connecting a ground plane to the second magnetic substrate, wherein said connecting comprises disposing the one or more cavities between the one or more antenna elements and the ground plane.
An antenna assembly comprising:
- a first magnetic substrate having a first surface and a second surface opposite from the first surface;
- one or more antenna elements disposed on the first surface of the first magnetic substrate;
- a microstrip feed line disposed on the second surface of the first magnetic substrate;
- a second magnetic substrate secured to the first magnetic substrate by a first laminate layer, wherein the second magnetic substrate comprises one or more cavities aligned with the one or more antenna elements and the microstrip feed line, and wherein the one or more cavities define an axial envelope that contains the one or more antenna elements and the microstrip feed line;
- a third magnetic substrate secured to the second magnetic substrate by a second laminate layer;
- and
- a ground plane secured to the third magnetic substrate, wherein the one or more cavities are disposed between the one or more antenna elements and the ground plane, wherein the microstrip feed line is disposed between the one or more antenna elements and the one or more cavities.
An antenna assembly comprising:
- a first magnetic substrate having a first surface and a second surface opposite from the first surface;
- one or more antenna elements disposed on the first surface of the first magnetic substrate;
- a microstrip feed line disposed on the second surface of the first magnetic substrate;
- and
- a second magnetic substrate secured to the first magnetic substrate, wherein the second magnetic substrate comprises one or more cavities aligned with the one or more antenna elements and the microstrip feed line, wherein the second magnetic substrate has a first surface and a second surface opposite from the first surface, wherein the one or more cavities extend through and between the first surface and the second surface of the second magnetic substrate.
