Mutli-layer CTS antenna array in PCB technology for SatCom applications

High-Gain Tapered Long Slot Array for Satcom Applications in PCB Technology With Folded Corporate Feed Network

“…This work focuses on the design of the linearly-polarized long slot array and its integration with a very broadband pillbox beamformer to cover with a single aperture the K/Ka band of Satcom applications over a large field of view (±42°i n elevation). Compared to our previous works [11], [14], [16], we present a novel design of a 64-slots tapered long slot array with a minimum measured gain of 30.8 dBi at 19.5 GHz. The long slot array is fabricated using PCB technology, while the pillbox beamformer is fabricated by CNC milling.…”

“…Lately, long slot arrays have become a popular choice for Satcom antennas due to their superior broadband, low profile, and wide-angle scanning capabilities [11]- [14]. These arrays use one radiating aperture to cover the full K/Kaband for transmission and reception [15]- [17], and when combined with a quasi-optical system, they offer mechanically or electronically controlled elevation beam steering and 2-D scanning via azimuthal rotation of the user terminal [18]- [20].…”
