“…Unlike conventional patch antennas, multiple radiating patches embedded on same or different substrates are stacked over a feeding substrate in a SAA topology. Frequency reconfigurability, mitigation of undesired parasitic effects, and polarization switching are important benefits of SAA other than the broader bandwidth aspect and directional radiation patterns with high gain . Having an eye on the benefits of SAA, researchers have been continuously working to explore its benefit and utilization of the SAA in the applications such as broadcasting, radars, space communication, and biomedical industry.…”

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 (λ g /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.

“…The results show that the gain increases up to 14.63 dBi if using air substrate compared to FR-4 substrate (9.04 dBi). In another novel antenna structure which contains five substrate layers [23], the eight-element antenna array with feeding network achieved frequency band from 5.28 to 6.05 GHz 15.4% and antenna gain of 16.24 dBi. Most of the reported papers in the literature are more complexes, high-cost, and have achieved a maximum bandwidth of 30% with gain below 16.24 dBi.…”

A broadband microstrip patch antenna, loaded E-U-shaped open slot on backward of radiating layer is proposed and experimentally investigated. The antenna employs a foam-filled dielectric substrate, whose dielectric constant is within the lower end of the range. The proposed antenna has been designed for electromagnetic analysis including the impedance bandwidth, reflection coefficient, radiation pattern, and antenna gain. The open slot is loaded on the back radiated layer, which is perpendicular to the radiating edge of the oblong microstrip patch component, where the symmetric line feed is selected. This new technique used to increase the bandwidth and the gain of antenna through increasing current path by slot location, width and length on backward of radiating Layer. The main structure in this research was a single microstrip patch antenna planar with three layers operating at two resonant frequencies 4.440 GHz and 5.833 GHz. All the simulated results are confirmed by two packages of electromagnetism simulation. An impedance bandwidth (S11 ≤ −10 dB) up to about 41.03% and 30.61% is achieved by individually optimizing its parameters. The antenna exhibits nearly stable radiation pattern with a maximum gains of 8.789 dBi and 9.966 dBi, which is suitable for Wi-Fi Band, satellite communications, and wireless presented. Whereas the results before this design that we have a proof of publication are 36.17% and 28.43%.
