“…The sequential‐phase feeding network is fabricated on substrate of Rogers4003 with a thickness of 0.813 mm to minimize the insertion loss. In Reference , a 10‐section power divider has proven to have a divider ability from 1 to 20 GHz. However, using the suspended strip line, structure is hard to make a compact feeding network.…”

This paper studies a unidirectional ultra-wideband circularly polarized (CP) spiral antenna array. The ultrawideband high-gain CP operation is realized by implementing four-element sequentially rotated spiral array antennas fed with an ultra-wideband feeding network. Tapered multisections power dividers and broadband microstrip-slot phase shifters are utilized to provide accurately equal power division and constant phase shifts of 90 . In order to further improve the CP operating bandwidth, foam of absorber is adopted between the radiating aperture and the feeding network substrate. The proposed CP array is designed, fabricated, and measured. Test results show that the impendence bandwidth of the proposed array covers 2.2 to 11.6 GHz (5.3:1) and 3 dB axial-ratio bandwidth covers 2.3 to 13 GHz (5.65:1), demonstrating a stable CP array performance within an ultra-wide working bandwidth.

“…Several methods have been proposed to overcome this problem. In Reference , a multisection Wilkinson power divider with suspended strip lines can achieve an ultra‐wideband. In References 16 to 19, the phase shifters utilize coupling by microstrip slots to get constant phase shift and low insertion loss across the band 3.1 to 10.6 GHz.…”

In this paper, a high power, air suspended stripline (SSL) T junction power divider at L band microwave frequencies is introduced. The power divider operating frequency is centered at 1.3 GHz. In this new configuration, the only dielectric used is air to have maximum power handling capability. An excitation transition from coaxial cable to the SSL transmission line is explained. The SSL was fabricated using aluminum sheets to gain the advantage of low cost. The power divider design was validated using circuit and 3D full wave simulations and confirmed using experimental measurements with all agreements. It has been proved that the power divider attenuation has sharp rejection characteristic at the designed frequency (−20 dB at 1.3 GHz). The power divider can be used as a feeder for devices used in high power applications.

A multi-section ultra-wideband Wilkinson power divider is presented in this article. The proposed device is developed based on a coplanar waveguide (CPW) to coplanar strip (CPS) transition, which is realized on a two-layer printed circuit board without using via holes. Equivalent circuit model of the proposed power divider is presented, and on that basis a three-section power divider with an ultra-wideband performance, ranging from 3 to 16 GHz is designed and numerically validated. Finally, prototypes of the proposed device is fabricated and measured to provide an experimental verification on the numerically predicted features, namely the operating bandwidth, input/output impedance matching, insertion loss, isolation between output ports, and amplitude/phase balance at output ports.
