Notch Antenna Having a Low-Profile Stripline Feed

Antennas are key components in wireless communication setups, with notch and array antennas being increasingly pivotal. From broadcasting to GPS, a broad range of applications require robust antennas that can effectively transmit and receive radio-frequency (RF) signals. At the same time, there is an ever-growing demand for slim, compact, and low-profile solutions, with stripline feeds being a typical answer. While stripline feeds fit the low-profile requirement, their traditional designs often struggle with efficient RF signal transfer. Existing solutions often cannot send the RF signal through the antenna effectively, resulting in signal loss or impedance mismatch. The usual problem is the lack of an efficient mechanism for facilitating seamless accessibility of the RF signals across multiple layers of the antenna. This operational inefficiency often results in suboptimal performance of wireless communication systems.

Technology Description

This technology introduces a notch antenna and an array antenna built on a low-profile stripline feed. The structure includes a dielectric substrate with conductive layers on both surfaces, each containing an opening. Nestled on the conductive layer of the upper surface is a notch antenna element, while a stripline embedded in the substrate runs below the antenna element. The central facility of this structure is the stripline's ability to couple and provide a seamless RF signal transfer between the stripline and antenna element, with a conductive via connecting the stripline to the opening in the lower surface, ensuring the RF signal is accessible. The technology's innovation stems from the elegant design integrating the upper and lower conductive layers, with the RF accessibility through the conductive via. The stripline's ability to couple the RF signal between the stripline and the antenna element is a unique facet as it facilitates efficient signal transmission and reception. The technology thus smartly combines antenna and stripline technologies to enhance the efficiency of RF signal transactions.
