In this work we discussed in details about the fabrication of a rectangular micro-strip antenna with an inclined slit of 100μm width for multi band operation. A simple rectangular micro-strip antenna is first designed for its operation in the S-band at 2.43 GHz. Then, we introduced a 100μm inclined slit on the antenna connecting the two radiating edges which results in multi band operation. Simulations are performed to study the effect due to the slit at different locations of the antenna with different angle of inclination. Prominent result of multi band operation in L and S-bands are observed with the slit introduced on it. Considering the simulation results, antenna prototypes with the best configuration are fabricated which show best results for multi band operations. Various parameters of the fabricated antenna are measured experimentally and are compared with the simulation results. The proposed method is simple and it can be fabricated easily to achieve best results.

“…Attainment of multiband is done by etching of inverted U-shapes and single fed mechanism. A defected ground structured quad band antenna with a gain range of 2.45 dB to 4.77 dB for satellite applications [16] is presented. Periodic square slots are etched on the ground surface to achieve quad band.…”

Antenna operating in multiple frequency bands has driven the demand of antennas. The design of Quad band microstrip patch antenna to attain multiband with improved gain is described in this paper. Several slits and slots are introduced in the design process to allow a sole antenna to operate in multiple bands. FR-4 Epoxy is used as a substrate material due to its low cost and effectiveness than other substrates. The antenna is built and corresponding geometry is simulated in high frequency structure simulator (HFSS) tool which is based on finite element method (FEM). The operating frequencies of the proposed antenna are 1.8089 GHz (1.46-2.24GHz), 4.64 GHz (4.57-4.71GHz), 5.3867 GHz (5.29-5.44GHz) & 12.9778 GHz (11.36-15.3GHz) with a reflection coefficients observed -15.59dB, -16.55dB, -33.15dB, -25.07dB respectively. Wide bandwidths 0.7767GHz and 1.4GHz are observed for primary and quad bands, narrow bandwidths are observed for second and third resonant bands. The gains are observed as 14.97 dBi, 3.81 dBi, 4.48 dBi, 3.92dBi for the respective operating frequencies. The radiation characteristics are observed semi -omni directional and omni-directional for the resonant bands. This antenna can be used in satellite radio, aircraft surveillance and some radar applications.

“…Slotted ground plane is accomplished by etching a flaw from the ground plane in a basic form. The ground plane faults will disturb the shielded current distribution, resulting in controlled excitation and electromagnetic wave propagation across the substrate layer [16][17][18]. Using the approaches described above, the proposed 2x2 microstrip array antenna is being constructed.…”

Microstrip patch antennas that are multiband and downsized are required to suit the high demand of modern wireless applications. To meet this need, a one-of-a-kind triple band array antenna has been proposed. The proposed 2x2 microstrip patch array, which comprises of four hexagon-shaped radiating patches are electromagnetically excited by a centrally positioned microstrip feed line in the same plane along with a slotted ground plane, is investigated. CST Microwave Studio, a powerful 3D electromagnetic analysis programme, was used to design and optimize the array antennas. The 2x2 array antenna was constructed on a FR-4 substrate with a dielectric constant of 4.3, a loss tangent of 0.001, and a height of 1.6mm. To optimize energy coupling from the feed line to the radiating patches, the ground plane has an H-shaped groove cut into it. The suggested 2x2 array antenna's multi- frequency behaviour is shown. Three resonant peaks were detected at 1.891GHz, 2.755GHz, and 3.052GHz. The observed bandwidths for these resonances are 234MHz, 69MHz, and 75MHz, respectively, with measured gains of 7.57dBi, 6.73dBi, and 5.76dBi. The goal of this work is to design, build, and test a single layer proximity fed array antenna. Standard proximity fed array antennas contain two substrate layers; however this array antenna has only one. As a consequence, the impedance matching and alignment are better. Simulated and experimental results showed that the this 2x2 array antenna operates in various important commercial bands, such as L and S bands and the array antenna might be beneficial for a wide range of wireless applications. The proposed antenna has good Impedance, S11, and radiation qualities at resonant frequencies. In this work, the 2x2 array antenna with hexagon-shaped radiating patches was successfully created utilizing the single layer proximity fed antenna concept and gap coupled parasitic patches.
