LEAKY-WAVE ANTENNA CAPABLE OF MULTI-PLANE SCANNING
First Claim
1. A leaky-wave antenna capable of multi-plane scanning, comprising:
- a substrate;
a first antenna series and a second antenna series, disposed on the substrate, and comprising a plurality of antenna units, wherein the first antenna series intersects with the second antenna series to share a predetermined antenna unit among the antenna units, and a part of the antenna units are connected in series to extend outwards from a first and a second transmission lines of the predetermined antenna unit to form the first antenna series, and the other antenna units are connected in series to extend outwards from a third and a fourth transmission lines of the predetermined antenna unit to form the second antenna series; and
a plurality of control units, disposed at peripheral of the predetermined antenna unit for controlling transmission paths between the first to the fourth transmission lines and the antenna units, and switching a leaky beam to one of a plurality of scanning planes, wherein the leaky beam scans along with a frequency variation through the antenna units.

Abstract
A leaky-wave antenna capable of multi-plane scanning is provided. The leaky-wave antenna includes a substrate, a first antenna series, a second antenna series and a plurality of control units. The first antenna series intersects with the second antenna series to share a predetermined antenna unit among many antenna units. A part of the antenna units is connected in series to extend from a first and a second transmission lines of the predetermined antenna unit to compose the first antenna series, and the other antenna units are connected in series to extend from a third and a fourth transmission lines of the predetermined antenna unit to compose the second antenna series. The control units control the transmission paths between the first to the fourth transmission lines and the antenna units, and switch a leaky beam to different scanning planes, wherein the leaky beam scans with frequency variation through the antenna units.
