A patch antenna with two rectangular elements is presented. The feeding mechanism introduces a phase shift between the elements excitation, as well as between the feeding points of each element. The Return Loss versus Frequency envelope which is then formed extends greatly as each feeding point contributes to the creation of a separate resonance. In this way, wideband operation at the 2.4 GHz WiFi...
A novel feeding mechanism for a rectangular patch antenna is introduced. A phase shift caused by path inequality between two possible symmetrical feeding points is introduced, in order to achieve wideband operation at the 2.4 GHz WiFi band. The idea is to create two separate resonances, by exploiting a phase shift in one of the feeds. Simultaneously activating the two feeds yields to an envelope formed...
