A window glass antenna for receiving AM and FM broadcast radiowaves in a diversity reception mode includes an inverted T-shaped antenna wire, a plurality of horizontal defrosting hot wires spaced from the inverted T-shaped antenna wire, an inductive coupling wire connecting the inverted T-shaped antenna wire and the horizontal defrosting hot wires to each other, power supply lines connected to the horizontal defrosting hot wires for energizing the horizontal defrosting hot wires, and first and second high-frequency blocking coils inserted in the power supply lines, the second high-frequency blocking coils being connected between the first high-frequency blocking coils and the horizontal defrosting hot wires. An AM broadcast signal can be received by the horizontal defrosting hot wires and portions of the power supply lines which are bounded by the first high-frequency blocking coils. A first FM broadcast signal can be received by the inverted T-shaped antenna wire, and a second FM broadcast signal can be received by the horizontal defrosting hot wires and portions of the power supply lines which are bounded by the second high-frequency blocking coils.
