“…However, utilization of vias to connect driven‐patch from feed line in multilayer topology along with the embedded vias of substrate‐integrated technology restricts its feasibility in practical applications . Similarly, a dual‐polarized 6 × 2 stacked microstrip antenna array covering 400 MHz bandwidth from 3.0 to 3.4 GHz for spacecraft application is presented . A dual frequency antenna at S/X‐bands with only 300 MHz from 2.375 to 2.675 GHz is discussed in ref.…”

This paper demonstrates the design procedure of a 4 × 8 phased array antenna. Initially, a unit element in multilayer topology with orthogonal slots in the ground plane to couple electromagnetic energy is designed. Then, a stacked patch with truncated edges is placed on the top thick substrate layer to enhance the bandwidth to 600 MHz. This multilayered stacked patch unit element is then used to design a 1 × 4 and 4 × 8 slot coupled stacked patch array. On the bottom side, a novel feedline structure is designed to provide a 90 o phase difference at the antenna feed for the circular polarization. The phase difference is achieved in the feedline structure using a quarter wavelength ( λg/4) difference in the lengths. After the numerical validation, both 1 × 4 and 4 × 8 stacked patch antenna arrays are fabricated to validate the simulations. The final 4 × 8 array achieved the target specification of an active reflection of less than −10 dB over 2.4 to 3.0 GHz, axial ratio of less than 3 dB, and stable radiation pattern over the complete band. In addition, beam scanning characteristics of the proposed stacked patch antenna arrays are also verified. The prototype resulted a peak gain of 19.5 dB at 2.7 GHz, 3‐dB beamwidth around 12 o in the xz‐plane, and scanning range of 90 o. Overall, good agreement between measured and simulated results showed that the proposed designed array capable of providing 600 MHz is an excellent candidate for the radar communication, small commercial drones, and synthetic aperture radar applications.

“…Feeding the microstrip patch antenna at two orthogonal edges, through edge feed or probe feed and hence exciting transverse magnetic TM 01 and TM 10 modes with orthogonal polarization, dualpolarized antennas can be realized [2,3]. As the impedance bandwidth of the antenna depends mainly on the feeding techniques, a maximum of 1.9% impedance bandwidth can be achieved using probe-fed microstrip arrays [4] and up to 15% with stacked structure [5][6][7].…”

A polarization matched 2×2 radiating array for electronically steered phased array antenna is presented. The antenna array is a multi-layer structure consisting of four square microstrip patch elements grown on each substrate to provide wide band operation at S-band. Dual polarizations of radiated wave from the antenna array have been achieved by feeding the array in series fed mode through horizontal and vertical ports. Designed 2 × 2 S-band dual polarized series fed antenna has been optimized on a finite element based ANSYS HFSS full wave solver. Controlling the amplitude of RF signal at input ports, the polarization can be matched to the target antenna polarization, hence antenna can work as polarization matched antenna. Gain of the developed antenna is 13 dBi, and the return loss is better than 10 dB over the frequency range of 2.3 to 2.5 GHz. This antenna can be used as radiating array for electronically steered phased array for S-band SOTM (SATCOM On The Move) application where the polarization of the antenna changes with movement of host platform.

We propose a low-profile dual-linearly-polarized unit cell in X-band, and its capability is demonstrated by a circularly polarized transmitarray. The unit cell comprises three metallic layers etched on two dielectric slabs without air gap. Cross strips are inserted in cross slots on the top and bottom layers, and the T-slot structure is etched on the middle layer. The proposed unit cell has high isolation between the dual polarizations, and its total thickness is only 1 mm. Prototype of a 341-element transmitarray, which transforms the incident linearly polarized wave into the outgoing circularly polarized wave, is also fabricated and tested. The measured results show that the proposed transmitarray realizes 3.5% (9.8-10.15 GHz) axial ratio bandwidth and 4% (9.7-10.1 GHz) 1-dB gain bandwidth. The measured peak gain at 10 GHz is 21.9 dBi, with the aperture efficiency of 36%.
