Phase Corrected Substrate Integrated Waveguide H-Plane Horn Antenna With Embedded Metal-Via Arrays

As traditional horn antennas that could be used as feeds for reflector antenna systems, substrate integrate waveguide (SIW) horns could be used as feeds for planar antennas and arrays. In this letter, a phase-and-amplitude-corrected SIW horn by metal-via arrays is presented as a planar feeding structure. The compact SIW horn is applied to feed two antipodal linearly tapered slot antenna (ALTSA) arrays, forming sum and difference beams at X-band. The measured gain of the sum beam is 12.84 dBi, the half-power beamwidth is , the FTBR is 15.07 dB, and the sidelobe level is 20.79 dB at 10.1 GHz. The null depth of the difference beam is 44.24 dB. Good agreement between the simulation and the measured results is obtained.Index Terms-Antipodal linearly tapered slot antenna (ALTSA), array antenna, feeding system, planar horn, substrate integrate waveguide (SIW).

“…According to the theory of array antenna, the phase shifts of each unit of the MS need to be compensated to adjust and control the electromagnetic waves propagation direction. The theory of phase compensation [5][6][7] of the transmission array antenna is based on the compensation of the path transmission from the center of the feeding antenna [8][9][10]. Most previous studies mainly focused on steering electromagnetic waves using uniform MSs [11][12][13][14][15][16].…”

In this paper, a new high-gain antenna with beam control based on multilayer non-uniform metasurfaces (MNMSs) is proposed. The MNMS consists of multilayer non-uniform square and ring metal patches array. The phase-shift of the MNMS element can achieve 310° with the variation of geometrical sizes. Moreover, four high-gain antennas based on MNMS element are designed, fabricated, and measured to realize 0°, 30°, 45°, and 60° beam control in pitching plane, respectively. Relative bandwidth of the proposed high-gain antenna is above 12%. The simulated and measured results of the proposed antennas show that the wide-angle and azimuth direction beam control capability can be effectively realized by integrating different MNMS with the feeding horn antenna.

“…One popular solution method to mmWs is the substrate integrated waveguide (SIW) [1]. Up to now, several different types of antennas based on SIW technology have been explored and developed [2]- [4]. Nevertheless, SIW has unavoidable dielectric losses in the substrate as the frequency increases.…”

In this paper, a cavity-backed full-corporate feed slot array antenna based on ridge gap waveguide at 140 GHz is presented. In order to fabricate the proposed slot array by computerized numerical control (CNC) milling technology, the length of metallic pins is selected as large as possible. Since the full-corporate feed networks are very dense, and only one row of metallic pins is required to isolate the coupling effect between any two neighbored distribution networks. In the work, height value of the bed nails are well selected so that the mutual coupling are below-20 dB. The simulated results show that the proposed array antenna has an input impedance bandwidth of 11% better than-10 dB. The bandwidth covers 135-150 GHz frequency band. The simulated gain is higher than 38 dBi over 135-150 GHz.
