Abstract:
A method for making a chip type antenna having a wide bandwidth, comprising the steps of:forming a recess extending from a front end surface to a rear end surface in a bottom portion of a substrate that contains a dielectric material or a magnetic material; forming a radiation electrode on a top portion of said substrate; forming a first grounding electrode on a portion of a first segment of the bottom portion of said substrate adjacent one side of said recess, leaving a gap on said first bottom segment between an extended end of said grounding electrode and said front end surface; forming a second grounding electrode on a portion of a second segment of said bottom portion of said substrate adjacent another side of said recess; forming a first portion of a feeding electrode on said first segment of the bottom portion of said substrate between said front end surface and said gap, said gap being between terminating ends of said first grounding electrode and said feeding electrode; forming a second portion of said feeding electrode on the front end surface of said substrate adjacent said first segment of the bottom portion of said substrate; and forming a shorting electrode on the rear end surface of said substrate for electrically connecting said radiation electrode to at least one of said first and second grounding electrodes.
