An N-way radio frequency (RF) divider/combiner is formed as a combination including an input port electrically coupled to a first 2-way divider/combiner and a second 2-way divider/combiner. An antenna may be coupled to at least one port of the N-way divider. The antenna may be formed as a compound printed loop (CPL) antenna. The N-way RF divider/combiner may be configured to provide N inputs and M output ports, wherein N and M are integers and any of the M output ports and N input ports can be connected to any combinations of devices. Such devices may include, e.g., an antenna including but not limited to a CPL antenna, RF receive port, transmit port, amplifier, RF switch, low noise amplifier (LNA), oscillator, tuning circuit, matching circuit, lumped element circuit, active circuit, diode, adjustable inductive circuit, and adjustable capacitive circuit.
