“…The monopole antenna had a planar CPW-G fed wideband structure with a rectangular radiator to achieve a more compact and wideband design that could be easily printed [20]- [22]. A CPW-G on the top and bottom layers is extremely suitable at shielding the antenna and the sensor data bus from interfering noise that may have coupled into the shared power supply traces in the bottom layer and also due to the digital switching within the MCU on the top layer [23].…”

Abstract-In this paper, the feasibility of inkjet printing of circuit and microwave structures on paper-based substrates is investigated for the first time in the implementation of a complete low-cost wireless platform for sensors. First, the system-level design of the module including the amplifier characterization were carried out to ensure optimum performance of the sensor modules in the UHF bands used in RF identification communication. These results were then used to design two different antenna structures, which are printed on paper along with their respective circuit layouts using inket-printing technology. Different techniques were investigated for the assembly of circuit components on the silver printed layouts. Finally, wireless link measurements on the assembled prototypes verified the good performance on the wireless and sensing sides.

“…However, the general focus has so far been on the antenna element but not so much on how the antenna can be used and integrated in a UWB system. Utilizing a flexible substrate the antenna can be bent and placed in many different ways without a major distortion of the antenna performance [11], [24]. Moreover, for a distortion free UWB communication an omnidirectional pattern and linear phase response are desired [25]- [27].…”

Two fully integrated dipole antennas with balun for ultra-wideband (UWB) radio utilizing a flexible and rigid printed circuit board are presented in this paper. The concept in this paper is to take advantage of the respective possibilities of the rigid and the flexible part. The balun utilizes broadside-coupled microstrips and is integrated in the rigid part of the printed circuit board, while the radiator is placed in the flexible part. The lower UWB band antenna with the balun covers the frequency-band 3.1-4.8 GHz (with margin) at VSWR<2.0. The upper UWB band antenna with the balun covers the frequencyband 6.0-8.5 GHz (with margin) at VSWR<2.0, and 5.5-11.0 GHz at VSWR<2.5.

“…Most CPW is used for slot antennas and printed monopoles in the previously published papers [9][10][11]. Owing to the characteristics of compact size, wide CP bandwidth, and omnidirectional radiation patterns, those kinds of antennas fit very well for conformal packaging and for wearable electronics [12,13]. However, slot antennas and monopoles have quite low gains and are not suitable for directional microwave transmission.…”

A novel design of 1×2 and 2×2 circularly polarized (CP) microstrip patch antenna arrays is presented in this paper. The two CP antenna arrays are fed by sequentially rotated coplanar waveguide (CPW) to slotline networks and are processed on 1 mm thick single-layer FR4 substrates. Both of the two arrays are low-profile and lightweight. An air-bridge free CPW-slotline power splitter is appropriately designed to form the feeding networks and realize the two CP antenna arrays. The mechanism of circular polarization in this design is explained. The simulated and measured impedance bandwidths as well as the 3 dB axial ratio bandwidths and the radiation patterns of the two proposed antenna arrays are presented. This proposed design can be easily extended to form a larger plane array with good performance owing to its simple structure.
