Abstract: In an aspect, an apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a transceiver, a memory, and at least one processor coupled to the memory and configured to execute instructions stored in the memory to control the transceiver. In another aspect, an apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a patch antenna coupled to the transceiver. The patch antenna includes a patch, a ground plane substantially located with respect to the patch, a probe feed coupled to the patch, and a slot-coupled feed configured to couple to the patch.

Abstract: Certain aspects of the present disclosure provide a directional coupler. In certain aspects, the directional coupler generally includes a first inductor and a second inductor wirelessly coupled to the first inductor. In certain aspects, the directional coupler generally includes an input port at a first terminal of the first inductor and a transmitted port at a second terminal of the first inductor. In certain aspects, the directional coupler generally includes a coupled port at a first terminal of the second inductor and an isolated port at a second terminal of the second inductor. In certain aspects, the directional coupler generally includes a first complex impedance component directly coupled to the isolated port and a second complex impedance component directly coupled to the coupled port.
