“…Furthermore, performance comparison of the proposed SMPA antenna with counterpart design in the literature 16,[33][34][35][36][37][38] has been presented in Table 5. As it can be seen from the table, the SMPA antenna design not only achieves better radiation performance but also has smaller size to its counterpart design in the literature.…”

With the ever‐increasing demands for high‐performance wireless communication systems, the need of fast and low‐cost realization of antenna stages had also become more crucial for wireless communication industry. Herein, design and low‐cost realization of a three‐dimensional (3D) printed dual band Stacked Microstrip Patch Array (SMPA) antenna has been studied. A 3D electromagnetic‐based simulation model of the proposed SMPA antenna has been created in CST Microwave Studio. The antenna achieves a simulated gain level of almost 8.3 dBi at 5.2 and 10.4 GHz frequencies. Then, the antenna design with optimally selected parameters has been prototyped via the use of 3D printing technology. The prototyped antenna has a measured gain level of 7.2 dBi at the operation frequencies. Furthermore, the experimental results of the prototyped antenna have been compared with the simulated results. From the compared results, it can be concluded that not only the proposed antenna design has achieved high‐performance measures compared with counterpart designs in the literature but also it is possible to achieve an accurate, fast, and low‐cost realization via the use of 3D printing technology.

“…In Table 1, the total patch area and substrate thickness are expressed in terms of the wavelength at the center frequency of the VSWR BW (λ c ). The proposed designs offer comparable BW and gain against the gap-coupled and stacked variations as reported in [10][11][12]. However, against these designs, the proposed antennas are planar in structure using single layer, and thus they are simpler to implement.…”

“…However, against these designs, the proposed antennas are planar in structure using single layer, and thus they are simpler to implement. Due to four times of the patch area, the stacked 2 × 2 MSA array using shorted patches and a power divider as reported in [10] offers higher antenna gain than the proposed antennas. Compared with the gap-coupled U-slot cut rectangular MSAs reported in [13], due to use of proximity feeding, proposed design offers higher impedance BW with smaller patch size and showing comparable values of peak antenna gain.…”

“…The multi-resonator gap-coupled technique increases BW and also adds to the gain [9]. By employing stacked configuration along with gap-coupled patches in the stacked layer, wideband and high gain MSA variations are reported which yields gain around 11 dBi [10][11][12]. The enhancement in gain is also realized by using either gap-coupled configuration of U-slot cut MSAs or array of U-slot cut patches fed using an L-probe feed employing power divider [13,14].…”

Wide bandwidth and high gain designs of sectoral microstrip antennas gap-coupled with parasitic arc shape patches are proposed. In 1800 MHz frequency band, optimum response with bandwidth of more than 50% and peak gain of 10 dBi is obtained for 30 • sectoral angle employing two gap-coupled arc shape patches. Further gap-coupled variations of slot cut single arc shape patch with 60 • sectoral patch is presented. This design yields bandwidth of above 930 MHz (∼ 53%) with peak gain of more than 10 dBi. The comparison for the proposed gap-coupled sectoral variations with reported antennas is presented. Proposed gap-coupled sectoral configurations are single layer and thus simple in design and yet offers bandwidth and gain of larger than 50% and 10 dBi, respectively.

“…Microstrip antennas are low cost, low profile, and light-weight structures which are one of the popular and interesting radiating devices in the engineering and sciences. Alongside these advantages, these antennas have an easy fabrication process and can be easily integrated into planar microwave subsystems and circuits [1][2][3][4][5][6][7][8][9]. In many applications of array antenna, the cost, complexity, and size are significant and important challenges in the implementation.…”

A new class of the wideband series-fed microstrip array antenna is presented for X-band applications. A novel configuration of the reflector-slot-strip-foam-inverted patch (RSSIP) is proposed to provide high efficiency and wide operating frequency band. To improve the front to back ratio (FBR) and enhance the gain, a reflector is used. The series-fed configuration is selected for the array to simultaneously provide a very high efficiency and reduce the side lobe level. To experimentally verify the performance, a prototype of the array antenna is fabricated, and measurement is performed. This array consists of 12 sub-linear arrays with series-fed microstrip excitation. Also, each of these subarrays consists of 16 RSSIP antennas. An excellent agreement exists between measurement and simulation. The measured gain and efficiency of the fabricated antenna are 28.5 dB and 67% at 10 GHz, respectively. The measured impedance matching bandwidth (S 11 < −10 dB) is 24% which confirms the wideband characteristic of the antenna. The series-fed configuration results in very low measured SLL of −24.5 dB at H-plane. The proposed 16×12 array antenna is a proper candidate for applications in MIMO systems and synthetic aperture radars (SAR).
