“…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. It exists a sequential rotation network (SRN) too, which could answer to our constraints [7].…”

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.

“…According to the structures of feed network, hollowwaveguide based mmW slot array antennas can be divided into two categories: one is series-feed [5], [6] or partial cooperatefeed [7], [8] and the other is full corporate-feed [9][10][11]. The former generally has a simpler structure, but usually suffers from narrow bandwidth [12][13][14].…”

“…In contrast, the full corporatefeed array antenna exhibits a wider bandwidth. MmW full corporate-feed slot array antennas have been reported in [9][10][11], [15][16][17][18][19][20][21]. In [17], a W-band slot array antenna with fractional bandwidth (FBW) of 21% (85 -105 GHz) and a peak gain of over 30 dBi was presented.…”

“…In addition, GW is easier and cheaper to be manufactured by using conventional low-cost manufacturing [14,15]. There have been several designs of circularly polarized antenna based on GW [16][17][18][19]. In [18], a low profile 4 × 4 single layer array is designed.…”

“…The antenna has a simple structure and is fed by a combination of ridge gap waveguide (RGW) and groove gap waveguide (GWG), showing the possibility of large array design. In [19], a 3-layer high-gain RHCP antenna is realized. The whole antenna array is excited by sequentialphase feeding network and has 21.8% axial ratio (< 3dB) bandwidth and 23.5 dBi gain.…”

In this paper, two different configurations of dual circularly polarized antenna elements in single layer gap waveguide (GW) are presented for 77GHz automotive radar systems. Both of the antenna configurations utilize slot element to radiate and generate circular polarizations. The right-hand circular polarization (RHCP) and the left-hand circular polarization (LHCP) are generated at the same working frequency with different input ports. The simulated results show that both two antenna elements could cover the proposed impedance bandwidth (75-80 GHz) with an axial ratio lower than 2 dB.
