Antenna module
First Claim
1. An antenna module comprising:
- an antenna having a base, and a pair of terminals and a conductor formed on the base;
a power supply, supplying power to one of the pair of terminals;
an opening, connected to the other of the pair of terminals;
an antenna substrate, on which the antenna is mounted;
a grounding area, formed in the vicinity of the power supply; and
a peripheral conductor, formed at least a portion on the periphery of the antenna substrate, wherein the peripheral length of the peripheral conductor formed on the periphery of the antenna substrate is nearly integer times as long as 0.2 wavelength to 0.3 wavelength of a resonance frequency.
