Abstract

A phased antenna array in a package is provided. The phased array antenna in a package comprises an antenna array with an integrated passive beamformer network, and at least one actuation mechanism. The passive beamformer network comprises at least one phase shifter, and each of the at least one phase shifter comprises a transmission line having a slow-wave structure and a ceramic. Each of the at least one actuation mechanism comprises a magnet and an electromagnet coil, where the magnet is coupled to the ceramic. The at least one actuation mechanism configured to increase or decrease a gap between the transmission line and the ceramic.

Claims (14)

5. The phased antenna array package of claim 1 , wherein each of the at least one phase shifter has a low insertion loss.

6. The phased antenna array package of claim 1 , wherein the antenna array comprises 16 antenna elements, and wherein each antenna element is integrated with one of the at least one phase shifter and one of the at least one actuation mechanism.

7. The phased antenna array package of claim 1 , wherein the at least one phase shifter provides a tuning range of 330°.

8. The phased antenna array package of claim 1 , wherein the ceramic is a high dielectric ceramic.

9. The phased antenna array package of claim 8 , wherein the ceramic has a dielectric constant of 60.

10. The phased antenna array package of claim 1 , wherein an antenna element of the antenna array is an elliptical patch antenna for generating a circular polarization wave.

11. The phased antenna array package of claim 1 , wherein an antenna element of the antenna array comprises a metal layer that includes a slot.
