A dual resonant wideband meandered PCB antenna is disclosed. The antenna includes two meandered paths that are joined at a common feeding path. The meandered paths have different lengths, which results in different resonance frequencies. The antenna may also include a short circuit stub connected to the feeding path for impedance matching. In some embodiments, the antenna is formed on one layer of a printed circuit board. In another embodiment, to conserve space, the antenna may be formed on multiple layers of the printed circuit board.

Dual resonant wideband meandered PCB antenna

An apparatus includes an RF apparatus, and a wideband multi-band matching balun. The wideband multi-band matching balun includes a multi-band balun, which includes at least one three-element frequency-dependent resonator (TEFDR). The wideband multi-band matching balun further includes a differential-to-differential matching circuit coupled to the RF apparatus. The differential-to-differential matching circuit includes at least one TEFDR.

Radio-frequency apparatus with multi-band wideband balun and associated methods

An apparatus includes a substrate and a loop antenna formed using the substrate. The loop antenna includes a set of gaps formed to isolate a first part of the loop antenna from a second part of the loop antenna.

Apparatus with partitioned radio frequency antenna and matching network and associated methods

An apparatus includes a radio-frequency (RF) apparatus, and a multi-band matching balun coupled to the RF apparatus. The multi-band matching balun including a plurality of capacitors and a plurality of inductors. None of the plurality of capacitors and none of the plurality of inductors is variable or tunable.

Radio-frequency apparatus with multi-band balun and associated methods

An apparatus includes an RF apparatus, and a multi-band matching balun coupled to the RF apparatus. The multi-band matching balun includes at least one three-element frequency-dependent resonator (TEFDR) and at most three reactive elements.
