“…The array antenna with the same gain as the parabolic antenna requires thousands of antenna elements. And each element of phased-array antenna is equipped with a separate power amplifier unit and phase shifter, a large number of amplifiers and phase shifters will make the cost of the antenna array extremely expensive, thus lost its practical applicability [5] [6]. If the gain of the antenna element is high, the number of antenna elements can be greatly reduced, thus reducing the cost of the antenna array.…”

Abstract. The reference source system is a key factor to ensure the successful location of the satellite interference source. Currently, the traditional system used a mechanical rotating antenna which leaded to the disadvantages of slow rotation and high failure-rate, which seriously restricted the system's positioning-timeliness and became its obvious weaknesses. In this paper, a multi-beam antenna scheme based on the horn array was proposed as a reference source for the satellite interference location, which was used as an alternative to the traditional reference source antenna. The new scheme has designed a small circularly polarized horn antenna as an element and proposed a multi-beamforming algorithm based on planar array. Moreover, the simulation analysis of horn antenna pattern, multi-beam forming algorithm and simulated satellite link cross-ambiguity calculation have been carried out respectively. Finally, cross-ambiguity calculation of the traditional reference source system has also been tested. The comparison between the results of computer simulation and the actual test results shows that the scheme is scientific and feasible, obviously superior to the traditional reference source system.

“…In fact, the gap waveguide technology uses the cut-off of a PEC-PMC parallel plate waveguide to control desired electromagnetic propagation between the two parallel plates without the requirement of electrical contact. To date, some array antennas have been realized based on gap waveguide technology in 10-15 GHz frequency band [29][30][31]. The first millimeter wave array antenna was the PCB-based inverted microstrip ridge gap waveguides [32], but it had considerable loss and it was expensive to manufacture all the via holes.…”

 Abstract-A wideband, high gain high efficiency 16×16-element slot antenna array is presented for 60 GHz band applications. The antenna is designed based on gap waveguide technology. The most important advantage of using this technology is its ability to decrease complexity and cost of fabrication because there is no requirement of electrical contact between the three layers of the antenna structure. The three layers are a corrugated metal plate with radiating slots, a sub-array cavity layer, and a ridge gap waveguide feed network layer. The corporate feed network is realized by a texture of pins and guiding ridges in a metal plate. Also, in order to excite the antenna with a standard V-band rectangular waveguide, a transition from ridge gap waveguide to WR-15 is designed. The radiating elements, corrugations, cavity layer, power dividers and transition are designed and optimized to suppress the reflection coefficient at the input WR-15 port over the desired frequency range from 57 to 66 GHz. Finally, the 16×16-element slot antenna array is fabricated by standard milling technology. Measured results demonstrate about 16% of reflection coefficient bandwidth (|S 11 | < -10 dB) covering 56-65.7 GHz frequency range, and the measured gain is larger than 32.5 dBi over the band with more than 70% antenna efficiency.Index Terms-Slot array antenna, corporate feed network, gap waveguide, high gain antennas, 60-GHz frequency band.

“…Therefore, the gap waveguide technology has a large potential for millimeter wave applications. To date, some array antennas have been realized based on gap waveguide distribution networks: a 4×4 horn array at 15 GHz fed by inverted microstrip gap waveguide in [6], a 4×4 slot array at 60 GHz fed by microstrip-ridge gap waveguide, a 4×1 slot array fed by ridge gap waveguide [8]. In addition, recently, the use of gap waveguide distribution networks for design of W-band 8×8 slot arrays has been reported in [9,10].…”
