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.
Claims18
A wideband antenna apparatus, comprising:
