“…Different structures of the feeding network are proposed in the literature. The system designed in [5] is a combination of Wilkinson power dividers and two branch-line couplers in the 2.5 GHz band. Another design is proposed in [6], consists of three T-junction in phase power dividers for 30 GHz frequency band.…”

In this paper, the design of a miniature antenna dedicated to the detection of airliners through the demodulation of Automatic Dependence Surveillance-Broadcast system (ADS-B) signals is presented. This antenna is designed for being embedded on the top of a drone in order to detect and avoid collisions with airliners. This antenna consists of an array of Planar Inverted-F Antennas, a quadrature feed network (FN) and a reflector plane (RP). The FN is designed to have output signals with the same amplitude and a 90° phase difference between each other. It achieves circular polarization and maintains the axial ratio of the antenna under −3 dB at the desired frequency (1.09 GHz). The antenna with the FN was manufactured and characterized. It weighs approximately 145 kg with its RP. The measured gain of the proposed antenna is about +3.7 dBi. To validate the design, the manufactured antenna was tested with a Universal Software Radio Peripheral for the processing of ADS-B signals at the French National Microwaves Days 2019 (JNM) student contest. The detection of airliners can reach up to 437 km.

“…Power divider (PD) is a fundamental passive circuit usually used as a feeding network for antennas array [2][3][4][5][6][7]. It can be not only employed with antenna arrays but also used in power amplifiers [8][9][10][11] and mixers [12][13][14].…”

This paper presents a single stage 2-way Wilkinson Power Divider (WPD) suitable for Internet of Things (IoT) low frequency applications in the band from 200 MHz to 1 GHz. It is realized using a meandered line, and an open shunt stub matching network is added to get a compact structure. Moreover, a Vertical Periodic Defected Ground Structure (VPDGS) is added below each arm in order to improve the performance at the center frequency without adding extra length to the divider. The size of the proposed power divider is 30 × 15.3 mm 2 (0.082λ g × 0.041λ g ). The fabricated power divider achieves a fractional bandwidth of 107%, an input return loss of better than 10 dB, an output return loss of 20 dB, an isolation of better than 10 dB, and maximum exceeded insertion loss of 0.9 dB. The proposed compact power divider is implemented on Rogers RT/Duroid 5880 with thickness 0.254 mm in order to bend on any conformal surface.

“…The ability of sequential rotation technique to improve the axial ratio (AR) characteristic, is one of the main reasons of using this method. There are different feeding networks with more complex structures . By comparing the sequential rotation techniques, with other feeding network techniques such as butler matrices or CORPS, the simplicity of this array antenna can be felt more.…”

In this article, a 2 × 2 circular polarized (CP) antenna array, which is using sequential rotation (SR) technique in feeding network, has been introduced. The feeding network uses two 90° arcs and several rectangular lines with the same width. The length of these elements is multiple of λg/4 to produce 90° phase difference in 4 outputs of feeding network. By connecting the patch elements to the feeding network, which have been surrounded with radiating patch elements, design of 2 × 2 patch array has been completed. This array antenna with an incomplete ground which helps to have a better impedance matching, has been caused to reach a wider axial ratio (AR) and impedance bandwidth. The prototype of the proposed antenna array is built to validate the antenna performance. By using these techniques, a common bandwidth of 1.15 GHz has been achieved for impedance bandwidth (S11 < 10 dB) and AR bandwidth (AR < 3 dB) and 7.5 dBi maximum gain. In addition, the gain is more than 4 dBi in desired frequency range. According to the frequency range of 2.8‐3.95 GHz, the proposed antenna is suitable for S‐band applications.
