Power combiner and fixed/adjustable CPL antennas
First Claim
1. A system, comprising:
- an N-way radio frequency (RF) divider/combiner comprising an input port electrically coupled to a first 2-way divider/combiner and a second 2-way divider/combiner; and
a third 2-way divider/combiner coupled to the input port and each of the first and second 2-way divider/combiners, wherein each 2-way divider is configured to receive electrical energy at a first, common port and guide said electrical energy to second and third ports, and whereinthe second and third ports are separated by a generally rectangular bridge bar having a width selected to match the impedance of one or more devices to be connected to the second and third ports, respectively, and a length selected to provide a separation between the two ports of substantially ¼
wavelength at a center point of an operational frequency of the system.

Abstract
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.

15. A system, comprising:
-
an N-way radio frequency (RF) divider comprising an input port electrically coupled to a plurality of 2-way dividers, wherein the N-way RF divider is configured to provide N inputs and M output ports, wherein N and M are integers; and wherein each 2-way divider is configured to receive electrical energy at a first, common port and guide said electrical energy to second and third ports, and wherein the second and third ports are separated by a generally rectangular bridge bar having a width selected to match the impedance of one or more devices to be connected to the second and third ports, respectively, and a length selected to provide a separation between the two ports of substantially ¼
wavelength at a center point of an operational frequency of the system; andwherein the first, common port is coupled to the bridge bar by a generally tapering microstrip section having a relatively thinner end and a relatively wider end, the relatively thinner end connected to the first, common port and the relatively wider end connected along a part of the length of the bridge bar, the generally tapering microstrip section providing a separation between the first, common port and each of the second and third ports of substantially ¼
wavelength at the center point. - View Dependent Claims (16, 17, 18, 19, 20, 21)
