“…Microstrip patch antennas have been extensively considered by researchers in recent decades due to their small structure, simple fabrication, low weight, and simplicity of integration with printed circuit elements [1][2][3]. With the development of modern communication systems in recent years, expansive studies have been conducted to increase the bandwidth of microstrip patch antennas along with characteristics such as low profile and cross polarization [3,4]. Various techniques like adding a parasitic strip around the radiative element [5,6], creating a slot in the patch [7,8], differential-feed [9,10], increasing the thickness of the substrate and stacking [11], and exciting different radiation modes [13][14][15] are presented for increasing said bandwidth.…”

A novel wideband microstrip patch antenna with nonuniform transmission line feed is presented using model predictive control. Nonlinear model predictive control (NMPC) is used to achieve a nonuniform transmission line that matches with the microstrip patch antenna. The transmission line is extended using cosine expansion with the impedance differential equation then being used as the dynamic NMPC equation to find the unknown coefficients of that cosine expansion. The transmission line is designed such that the impedance of the input port matches the impedance of the microstrip antenna at the resonance frequency and its adjacent frequencies. The proposed antenna's impedance is 5.15-5.85 GHz. In this bandwidth, the radiation pattern is stable; the cross polarization and back lobe are −30 dB and −20 dB, respectively. The error in the impedance bandwidth is about 4.2%. The simulation and measurement results are considered satisfactory.

“…Many techniques have been reported to increase BW and gain. The impedance BW in MSA is increased by employing multiple resonant modes in the patch which is obtained either by employing parasitic patches in the same or stacked layer or by using modified feeding techniques like proximity feed and L-probe feed or by embedding resonant slots [3][4][5][6][7][8]. Amongst all slot cut designs have been widely used.…”

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.

“…Different slot shapes like U-shape, V-shape, rectangular shape, etc. and their modified variations have been reported to widen the BW [1][2][3][4][5][6][7][8][9][10][11]. A detailed study to explain the functioning of slot cut wideband antennas in terms of modified patch modes is reported [12,13].…”

Wideband designs of nearly square microstrip antenna using two half U-slots and rectangular slots are proposed. The slots optimize the spacing in between the patch modified TM 11 , TM 20 , TM 02 , and TM 30 resonant modes to yield wideband response. The design with two half U-slots yields bandwidth of around 1000 MHz (∼ 50%) whereas that with an additional rectangular slot yields bandwidth of 1345 MHz (∼ 61%). Due to the presence of higher order modes, the proposed design offers higher cross polar radiation pattern across the entire bandwidth with the gain greater than 5 dBi. The formulations for the modified patch modes and subsequent redesign procedure are presented, which serve as a guideline in the designing of similar antennas around specific resonance frequency. With the given antenna characteristics, the proposed antennas will find applications in personal and mobile communication systems.
