First Claim
Patent Images
1. An antenna system of a mobile-communications device comprising:
- a monopole antenna coupled to a wireless signal subsystem;
a slot antenna coupled to the wireless signal subsystem,wherein the monopole antenna and the slot antenna are linearly polarized and co-planar;
an active feed structure including a first active feedline and a second active feedline, the first active feedline and the second active feedline each being coupled, respectively, to a common ground plane shared by the monopole antenna and the slot antenna, the first active feedline and the second active feedline coupling the monopole antenna and the slot antenna, respectively, to the wireless signal subsystem; and
a dummy feed structure including a first dummy feedline and a second dummy feedline that is each coupled, respectively, to the common ground plane, the first dummy feedline being symmetric to the first active feedline about an axis of symmetry, and the second dummy feedline being symmetric to the second active feedline about the axis of symmetry.

Abstract
Described herein are technologies that facilitate wireless communication with highly-isolated, dual-port antenna system. More particularly, an example antenna system that implements the technology includes a complementary pair of physically co-located antennas for signal transmission and/or reception. More particularly still, an example implementation of the disclosed technology is an antenna system that utilizes a monopole antenna symmetrically and physically co-located with a slot antenna in a shared antenna plane with a simple feed structure.
