Abstract (en)
A novel antenna topology with multiple inputs on a hybrid slot-type antenna radiating element is realized on two layers of a printed circuit board using multiple feeders connected to a central conductive surface on a first layer and multiple slots connected to a central non-conductive surface on a second layer, the central surfaces having similar shapes but different sizes to create an interval that behaves as a slot antenna by radiating electromagnetic waves. To increase the decorrelation between the multiple directional radiation patterns corresponding to the different inputs the antenna uses a main printed circuit board as part of the antenna design to improve the decorrelation and the multiple inputs locations and multiple slot shapes are chosen in this objective. The antenna is adapted to be integrated directly in a receiver for the reception of broadcast television such as ATSC but can also be integrated into an indoor device connected to a television receiver. In this case, the indoor device would not require any installation nor particular positioning.
