Abstract
A slot antenna is disclosed for use in RF broadcasting. The antenna includes an elongated longitudinally extending hollow mast surrounding a longitudinal axis. An array of longitudinally spaced slots are formed in the mast for radiating electromagnetic energy therefrom. A coupler bar is associated with each slot. Each coupler bar is located within the mast between the ends of the associated slot for coupling electromagnetic energy from within the mast and developing with the slot a slot-coupler reactance. Tuning means is associated with each slot. Each tuning means is longitudinally spaced from the associated slot. Each tuning means extends inwardly from the mast toward the longitudinal axis for tuning the antenna to reduce the slot-coupler reactance.
