Abstract

A wideband antenna apparatus can include a ground plane on a printed circuit board, and a plastic substrate that can support an antenna metal structure of an antenna. The antenna can be part of an antenna assembly that can connect to the printed circuit board. The wideband antenna apparatus may further include a metal radiating element mounted to the plastic substrate with heat staking, and a feeder leg electrically connected to an RF feeder port. The antenna can be connected directly to the RF feeder port and the plastic substrate can control variations in the radiation performance of the antenna due to, for example, manufacturing variations.

First claim

What is claimed is:

1 . A wideband antenna apparatus, comprising:
a printed circuit board with a ground plane disposed on the printed circuit board; and an antenna assembly connected to the printed circuit board, wherein the antenna assembly comprises:
an antenna having an antenna metal structure comprising a feeder leg and a metal radiating element, wherein the antenna is connected directly to an RF feeder port through the feeder leg; and
a plastic substrate configured to:
support the antenna metal structure; and
control variations in a radiation performance of the antenna, wherein the metal radiating element is mounted on the plastic substrate with heat staking.

2 . The wideband antenna apparatus of claim 1 , wherein the plastic substrate comprises at least one of: polycarbonate (PC) and acrylonitrile butadiene styrene (ABS).

3 . The wideband antenna apparatus of claim 1 , wherein the antenna is directly soldered to the RF feeder port.

4 . The wideband antenna apparatus of claim 1 , wherein the antenna is partially potted.

5 . The wideband antenna apparatus of claim 1 , wherein the antenna metal structure of the antenna is configured to operate at narrowband Internet-of Things (NBIOT) frequencies.

6 . The wideband antenna apparatus of claim 5 , wherein the wideband NBIOT frequencies comprise frequencies in a range of 700 MHz to 2100 MHz.

7 . The wideband antenna apparatus of claim 1 , wherein the antenna corresponds to an LTE Internet-of-Things antenna.

8 . A wideband antenna apparatus, comprising:
an antenna having an antenna metal structure comprising a feeder leg and a metal radiating element, wherein the antenna is connected directly to an RF feeder port through the feeder leg; and a plastic substrate configured to:
support the antenna metal structure; and
control variations in a radiation performance of the antenna, wherein the metal radiating element is mounted on the plastic substrate with heat staking.

9 . The wideband antenna apparatus of claim 8 , wherein the plastic substrate comprises at least one of: polycarbonate (PC) and acrylonitrile butadiene styrene (ABS).

10 . The wideband antenna apparatus of claim 8 , wherein the antenna is directly soldered to the RF feeder port.

11 . The wideband antenna apparatus of claim 8 , wherein the antenna is partially potted.

12 . The wideband antenna apparatus of claim 8 , wherein the antenna metal structure of the antenna is configured to operate at narrowband Internet-of-Things (NBIOT) frequencies.

13 . The wideband antenna apparatus of claim 12 , wherein the wideband NBIOT frequencies comprise frequencies in a range of 700 MHz to 2100 MHz.

14 . The wideband antenna apparatus of claim 8 , wherein the antenna corresponds to an LTE Internet-of-Things antenna.

15 . A method of operating a wideband antenna apparatus, comprising:
controlling with a plastic substrate, variations in a radiation performance of an antenna, wherein:
the antenna having an antenna metal structure comprising a feeder leg and a metal radiating element,
the antenna is connected directly to an RF feeder port through the feeder leg,
the plastic substrate supports the antenna metal structure of the antenna, and
the metal radiating element is mounted on the plastic substrate with heat staking.

16 . The method of claim 15 , wherein the antenna is directly soldered to the RF feeder port.

17 . The method of claim 15 , wherein the antenna metal structure of the antenna is configured to operate at narrowband Internet-of-Things (NBIOT) frequencies.

18 . The method of claim 15 , wherein the antenna corresponds to an LTE Internet-of-Things antenna.
