PLANAR ANTENNA

This abstract first appeared for US patent application 18728610 titled 'PLANAR ANTENNA

Original Abstract Submitted

A planar antenna includes a dielectric substrate, a feed line on a first surface of the dielectric substrate that has a first and second lateral sides, three rectangular-shaped radiation elements arrayed on the first surface and provided at the first and second lateral sides to alternately protrude, and an electromagnetic band gap structure having an arrangement region on the first surface. The first surface includes a first adjacent region adjacent to the first lateral side and a second adjacent region adjacent to the second lateral side. The arrangement region includes a first arrangement region in the first adjacent region and a second arrangement region in the second adjacent region. Part of the first arrangement region is closer to the feed line with respect to a first imaginary line, and part of the second arrangement region is closer to the feed line with respect to a second imaginary line.
