Antenna module for a portable radio equipment with a grounding conductor

An antenna module comprising:

• a dielectric substrate molded in a predetermined shape;
• a grounding conductor in the form of a sheet provided on one surface of said dielectric substrate;
• an antenna element conductor in the form of a sheet provided on an opposite surface to said one surface of said dielectric substrate and having a substantially V-shaped folded end portion;
• and
• an adjusting member inserted into said V-shaped folded end portion,
• wherein said adjusting member is composed of a dielectric portion and a conductor in the form of a sheet provided on at least one of the surfaces of said dielectric portions, and said conductor has an electrical contact with said V-shaped folded end portion to determine an electrical distance from said grounding conductor to said end portion.

An antenna module comprising:

• a dielectric substrate molded in a predetermined shape having first and second portions as a unit;
• a common grounding conductor in the form of a sheet provided on one surface of said first and second portions of said dielectric substrate;
• a first antenna element conductor in the form of a sheet provided on an opposite surface to said one surface of said first portion of said the dielectric substrate;
• and
• a second antenna element conductor in the form of a sheet provided on an opposite surface to said one surface of said second portion of said dielectric substrate;
• a resonance frequency of said the first antenna element conductor being different from that of said second antenna element conductor,
• wherein said dielectric substrate has a vacant space between said first antenna element conductor and said common grounding conductor and a vacant space between said second antenna element and said common grounding conductor, and
• further comprising a dielectric adjusting member inserted into one of said vacant spaces so that the resonance frequencies of said first and second antenna element conductors are different from each other.

An antenna module, comprising:

• a dielectric substrate molded in a predetermined shape having first and second portions as a unit;
• a common grounding conductor in the form of a sheet provided on one surface of said first and second portions of said dielectric substrate;
• a first antenna element conductor in the form of a sheet provided on an opposite surface to said one surface of said first portion of said the dielectric substrate;
• and
• a second antenna element conductor in the form of a sheet provided on an opposite surface to said one surface of said second portion of said dielectric substrate;
• a resonance frequency of said the first antenna element conductor being different from that of said second antenna element conductor,
• wherein said first and second antenna element conductors have respectively looped leading ends to make the antenna module a P-type antenna.
