In this paper, microstrip antenna array is considered. The resolution of the array is considered to be (2X1). The dimensions of the proposed antenna (width and length in 'mm') are taken as 8.3 mm x 5.75 mm. Also to improve the radiation properties combined H and dual U slots are cut on the antenna array elements. The theoretical calculations are done according to the considered dimension parameters using the standard patch antenna parameters, where the resonant frequency is found out to be "11 GHz". Now the proposed antenna is simulated using HFSS software. The ground plane is considered with the dimensions 26 mm x 16 mm. The dielectric is taken to be FR4 epoxy substrate. Strip-line feeding (inset-fed) is used to feed the antenna array. The simulated results showed the proposed antenna to be working at 11.03 GHz with return loss of-31.10 dB and a VSWR of '1.05'. Also the results are compared with the H slot microstrip antenna array and the dual U slot microstrip antenna array. All the necessary findings are tabulated and plotted.

“…Slots can enhance performance without increasing the dimension of the patch. L-, U-, E-, T-, H-shaped slots [19][20][21][22][23] are common slot geometries reported in literature. A T-slot, as compared to others, is easy to incorporate onto the rectangular patch.…”

Magnetodielectric substrate gives a new dimension for reducing the size of the planar antennas. In this article, the patch size is reduced by taking a substrate with nano-sized nickel ferrite inclusions in LDPE polymer matrix. The antenna is made to operate in X and Ku bands by engraving T slots along the resonant length of the patch. Structural modification of the substrate geometry as a step profile is incorporated along the slotted patch edges to enhance performance. The T-slots, along both the resonating lengths with the magnetodielectric stepped substrate show four resonant frequencies in both X-and Ku-bands with S 11 < −15 dB and a maximum −10 dB bandwidth of 22.4%. A miniaturization factor of 2.97 is obtained.

“…Various types of slot loading multi-band antennas were reported. In [3], Tao Ni et al . states that multiple operating bands, stable antenna gain, and almost an omni-directional radiation pattern can be achieved by loading T-shaped slots in the terminals of a T-shaped antenna with good impedance matching.…”

Compact modified T-slot circular patch antenna for multiple input multiple output (MIMO) applications, which has good response for four operating frequency bands is developed. Here the design consists of a circular patch with a new slot loaded T- shape on one side of the substrate and a feeder line on the other side of the substrate. A shorting pin is located between the patch and the feeder line. This proposed antenna resonates at the frequencies of 2, 4.8, 5.4, and 6.2 GHz covering the S-band, C-band, and LTE applications. The independent tuning of frequency bands is achieved by varying the length of the slots. By independent tuning of frequency bands, the selection of interested frequency band is achieved. The single element with miniaturized size of 1.945λ × 1.945 λ (30 × 30 mm2) is achieved including the feed line. The antenna has been tested for MIMO applications. The measured envelope correlation coefficient between the two elements, which are spaced 0.139 λ is <0.1(low correlation) and mutual coupling is found to be in the range of −20 dB to −80 dB. The simulation and measurement results of reflection coefficient, mutual coupling, and radiation pattern are presented.
