  • Method and system for multiple feed point antennas
    Patent number: 9397393
    Abstract: An antenna, including a radiating element configured to have a fundamental resonance frequency being regarded as a first harmonic resonance frequency fo, and feed points positioned on the configured radiating element at selected multiple locations that correspond to where a multiple of the first harmonic resonance frequency have current maxima, wherein feeds at the feed points cooperate at an operating frequency of the antenna to constructively combine their respective antenna radiation patterns.
