Abstract: An electronic device may be provided with an antenna module having a substrate. An antenna may be disposed on the substrate. The antenna may have a directly fed patch and parasitic patches. The antenna may be fed by a feed via. The parasitic patches may include a first layer of parasitic patches separated by a gap overlapping the directly fed patch. The parasitic patches may include an additional parasitic patch formed in a second layer. The additional parasitic patch may overlap the gap. A floating ground via may couple a center of the additional parasitic patch and a center of the directly fed patch to a landing pad in a ground layer. The landing pad may short the via to the ground layer at the radiating frequency of the antenna. The landing pad may be electrically floating at DC frequencies.

Abstract: An electronic device may be provided with a flexible printed circuit and a rigid printed circuit mounted to the flexible printed circuit using a board-to-board (B2B) connector. The flexible printed circuit may include signal conductors coupled to one or more antennas on the rigid printed circuit through the B2B connector. A given one of the signal conductors may include a phase shifter segment on the flexible printed circuit and/or a thick impedance matching segment on the rigid printed circuit that help to form a smooth impedance transition from the flexible printed circuit to the rigid printed circuit and the antenna(s). The B2B connector may include signal contacts interleaved with a ground contacts. The B2B connector may include ground bars laterally surrounding the signal and ground contacts to maximize the strength of mechanical coupling between the flexible printed circuit and the rigid printed circuit.
