<p>This paper presents Dual-Band proximity coupled feed rectangular Microstrip patch antenna with slots on the radiating patch and Defected Ground Structure. Initially a simple proximity coupled feed rectangular Microstrip patch antenna resonating at 2.4 GHz is designed. Etching out a ‘Dumbbell’ shaped defect from the ground plane and ‘T’ shaped slot from the radiating patch of the proximity coupled feed rectangular Microstrip patch antenna, results in a Dual-Band operation, i.e., resonating at 2.4 GHz and 4.5 GHz; with 30.3 % and 18.8% reduction in the overall area of the patch and the ground plane of the reference antenna respectively. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 123.6 MHz and C-band at frequency of 4.5 GHz with bandwidth of 200 MHz, and a very good return loss of -22.1818 dB and -19.0839 dB at resonant frequency of 2.4 GHz and 4.5 GHz respectively is obtained. The proposed antenna is useful for different wireless applications in the S-band and C-band.</p>

<p>This paper presents the bandwidth enhancement of a Proximity Coupled Feed Rectangular Microstrip Patch Antenna using a new Defected Ground Structure - an ‘inverted SHA’ shaped slot on the ground plane of the proximity coupled feed rectangular Microstrip patch antenna. The parameters such as Bandwidth, Return loss, VSWR and Radiation efficiency are improved in the proposed antenna than simple proximity coupled feed rectangular Microstrip patch antenna without Defected Ground Structure. A comparison is also shown for the proposed Microstrip patch antenna with the antenna structure without Defected Ground Structure. The proposed antenna resonates in S-band at frequency of 2.4 GHz with bandwidth of 180 MHz. A very good return loss of -47.9223 dB is obtained for the Microstrip patch antenna with an ’inverted SHA’ shaped Defected Ground Structure. Implementing an ‘inverted SHA’ shaped defect in the ground plane of the proximity coupled feed rectangular Microstrip patch antenna results in 5.3% improvement in bandwidth with 16.01% reduction in the overall area of the ground plane as compared to the Microstrip patch antenna without Defected Ground Structure.</p>

Rectangular Microstrip Patch Antenna

Communication applications require wide band and highly directive planner antennas. For such requirement this work deals with the analysis and simulation of a rectangular microstrip patch antenna loaded with INTERCONNECTED SRR metamaterial structure at a height of 3.2mm from the ground plane. The work also investigates the potential properties of the proposed metamaterial structure. The proposed Antenna is designed at a operating frequency of 2.75GHz to meet S-Band (2-4GHz) applications. By loading Interconnected SRR metamaterial structure with the rectangular patch antenna at a height of 3.2mm, the antennas bandwidth is found to be increased up to 378MHz and return loss is reduced to -42.2dB i.e. the potential properties like return loss, bandwidth, directivity and total efficiency of the proposed antenna increases to a great extent in comparison to the rectangular patch antenna alone. Double Negative properties of metamaterial have been proved by Nicolson-Ross-weir (NRW) method.

In this work a dual band rectangular microstrip patch antenna along with the innovative metamaterial structure is proposed at a height of 3.2mm from the ground plane, which consists of a rectangular geometry incorporated with c shaped structure. This work is mainly focused on increasing the potential parameters of microstrip patch antennas and analyzing the dual band operation of proposed antenna. The proposed antenna is designed to resonate at 2.478GHz and 2.919GHz frequency. The impedance bandwidth of the patch antenna along with the proposed metamaterial structure at 2.478GHz is improved by 20.4MHz and return loss is reduced by 20.128dB. At 2.919GHz the impedance bandwidth is improved by 25.4MHz and return loss is reduced by 19.564dB. For verifying that the proposed metamaterial structure possesses Negative values of Permeability and Permittivity within the operating frequency ranges, Nicolson-Ross-Weir method (NRW) has been employed. For simulation purpose CST-MWS Software has been used.

Defected Ground Structures

In this paper, two novel defected ground structures (DGS) are proposed to improve the return loss, compactness, gain and radiation efficiency of rectangular microstrip patch antenna. The performance of antenna is characterized by the shape, dimension & the location of DGS at specific position on ground plane. By incorporating a peacock shaped slot of optimum geometries at suitable location on the ground plane, return loss is enhanced from -23.89 dB to -43.79 dB, radiation efficiency is improved from 97.66% to 100% and compactness of 9.83% is obtained over the traditional antenna .Simulation results shows that the patch antenna with star shaped DGS can improve the impedance matching with better return loss of -35.053 dB from -23.89 dB and compactness of 9% is achieved. In the end comparison of both DGS shapes is carried out to choose one best optimize one. The proposed antennas are simulated and analyzed using Ansoft HFSS (version 11.1) software.

This paper presents the prototype and simulations of a compact rectangular microstrip patch antenna for ultra-wideband applications. The proposed antenna is printed on FR4 (Flame Retardant) substrate with relative permittivity of 4.4, dielectric loss tangent of 0.0024 and the dimensions of 57 × 25 × 1.57 mm3 . The radiating patch of the antenna is loaded with two rectangular stubs along its upper and lower edges and an equilateral triangular notch is truncated from the reduced ground plane to achieve optimum results in terms of bandwidth and reflection coefficient. It is fed along the centerline of symmetry by 50Ω microstrip feed line. The simulated return loss ( ) characteristics show that the proposed antenna has a capability of covering the wireless bands from 0.17GHz to 7.25GHz with impedance bandwidth of 7.08GHz and exhibits a peak gain of 5dB at 7.25GHz which is acceptable for UWB systems.

<p>This paper presents an efficient proximity coupled feed rectangular microstrip patch antenna with reduced harmonic radiation. The proposed antenna resonates in S-band at frequency of 2.45 GHz with bandwidth of 88.5 MHz. A very good return loss of -47.0546 dB is obtained for the Microstrip patch antenna. The antenna matching can be achieved with an appropriate line-patch overlap, but with a careful design consideration. Not only the good matching of the fundamental mode, but also the effect on the harmonic radiation from the other patch modes has been considered. Varying the length &amp; location of the microstrip feed line and introducing a defect in the ground plane- the harmonic radiation from the other patch mode is reduced to minimum.</p>
