Multi polarization conformal channel monopole antenna

摘要

A conformal channel monopole antenna system includes: a housing; a cavity formed within the housing; and a substrate covering the cavity. The substrate includes a first elongated radiating element coupled to two opposing sides of the top surface of the housing at two opposing ends in a first direction; a second elongated radiating element coupled another two opposing sides of the top surface of the housing at two opposing ends in a second direction orthogonal to the first direction; a first feed port at one end of the first elongated radiating element; and a second feed port at one end of the second elongated radiating element. The first elongated radiating element is configured to radiate a first type of polarization and the second elongated radiating element is configured to radiate a second type of polarization simultaneously with the first type of polarization.

1. A conformal channel monopole antenna system comprising:
a housing having a top surface; a cavity framed within the housing; and a substrate on the housing and placed on top of the cavity, and having a top surface, the substrate-including
a first elongated radiating element trace formed on the top surface of the substrate by a first conductive trace and coupled to two opposing sides of the top surface of the housing at two opposing ends in a first direction, wherein the first elongated radiating element has a narrower shape at its two opposing ends than its center;a second elongated radiating element trace formed on the top surface of the substrate by a second conductive trace and coupled to another two opposing sides of the top surface of the housing at two opposing ends in a second direction orthogonal to the first direction, wherein the second elongated radiating element has a narrower shape at its two opposing ends than its center;a first feed port directly connected to one end of the first elongated radiating element trace; anda second feed port directly connected to one end of the second elongated radiating element trace, wherein the first elongated radiating element trace is configured to radiate a first type of polarization and the second elongated radiating element trace is configured to radiate a second type of polarization simultaneously with the first type of polarization, and wherein the first elongated radiating element trace and the second elongated radiating element trace are configured to form said monopole antenna system.
