Electronic devices with hybrid antennas
First Claim
1. An electronic device, comprising:
- a housing having a metal wall;
a hybrid planar inverted-F slot antenna, wherein the hybrid planar inverted-F slot antenna has slot antenna structures formed from a slot in the metal wall and has planar inverted-F antenna structures, the planar inverted-F antenna structures include a ground feed terminal, a positive feed terminal, and a return path leg, the return path leg and the ground feed terminal are coupled to the metal wall on first and second opposing sides of the slot respectively, the positive feed terminal is coupled to the planar inverted-F antenna structures at the second side of the slot, and the positive feed terminal is separated from the metal wall of the housing by a gap;
an indirectly fed slot antenna; and
transceiver circuitry coupled to both the hybrid planar inverted-F slot antenna and the indirectly fed slot antenna.

Abstract
An electronic device may be provided with hybrid planar inverted-F slot antennas and indirectly fed slot antennas. A hybrid antenna may be used to form a dual band wireless local area network antenna. An indirectly fed slot antenna may be use to form a cellular telephone antenna. Antenna slots may be formed in a metal electronic device housing wall. The housing wall may have a planar rear portion and sidewall portions that extend upwards from the planar rear portion. The slots may have one or more bends. A hybrid antenna may have a slot antenna portion and a planar inverted-F antenna portion. The planar inverted-F antenna portion may have a metal resonating element patch that is supported by a support structure. The support structure may be a plastic speaker box containing a speaker driver that is not overlapped by the metal resonating element patch.
