“…Although large BW is obtained here, structural complexity of the antenna is increased. Dual-band antenna [4] is realized using two patch radiators suspended over ground plane, but resulting structure has relatively thick substrate about 0.09λ. Miniaturized dual-band antennas are achieved by incorporating multiple ground slots [8,9] and result in 64% and 46% size reduction, respectively.…”

“…Several techniques have been reported in the literature to attain dual-or multi-band characteristics. Multi-band antennas can be realized using multi-resonators or multi-layer structures, wherein additional resonant patches are electromagnetically coupled with the fed patch [1][2][3][4]. Here appropriate dimensions and spacing among the patches lead to multi-band response.…”

New designs of dual and triple band rectangular microstrip antennas employing modified ground plane profiles are proposed. Slots introduced in the ground plane not only tune the higher order mode resonance frequency of the radiating patch but also alter the current distributions on the ground which yields multi-band response showing reduced cross polar level radiation pattern. Dual and triple band antennas yield 1 to 2% of impedance bandwidth at each frequency with gain around 1.5 to 2 dBi. Also in the multi-band design, 35% reduction in patch size against the conventional half wavelength counterpart is obtained. Further resonant length formulation at modified patch modes is presented which gives closer prediction of calculated frequency than the simulated value. The proposed multi-band design can find applications in personal communications systems requiring frequency agile capabilities.

Abstract-The goal of this paper is to use defected ground structure (DGS) in microstrip antennas for dual band operation at microwave frequencies. The soft nature of the DGS facilitates improvement in the performance of microstrip antennas. A design study on microstrip patch antenna with specific DGS slot has been presented in the proposed work. In this paper, a stacked microstrip patch antenna (SMPA) has been designed for broadband behavior, and then skew-F shaped DGS has been integrated with a detailed study of possible DGS slots in a small area for dual band operation. The design and optimization of both the SMPA and DGS structures along with the parametric study were carried out using CST Microwave Studio V.9. Further, the dual band antenna, i.e., the SMPA with skew-F shaped DGS, has been fabricated, and the experimental results have shown a good agreement with the simulation ones.

“…Therefore, a dual-band antenna is preferred for its simple system configuration and cost Manuscript reduction. The existing planar dual-band antenna elements with stable broadside radiation patterns [7] could not be readily arranged to form an array with controlled radiation pattern. Planar dual-band antenna array designs have been achieved by employing high order modes slotted waveguide [8].…”

A planar dual-band antenna array for point-to-point communication is presented. The proposed compact antenna array operates at 2.4-2.5 GHz (4%) and 5.1-5.5 GHz (7.5%) with 11 10 dB, and corresponding gains of 11-13.3 dBi and 10.6-14.5 dBi respectively. It consists of four branches suspended at a height of 5 mm above a 250 250 mm ground plane. Each quarter consists of a series-fed meandered step-impedance filter connected to a L-shaped radiator, and they transverse horizontally away from the epicenter. The insertion loss method with non-redundant synthesis for filter design is applied to control the radiation aperture of the antenna array, allowing both the 2.4 GHz and 5.5 GHz radiators to co-exist and operate independently. A stable broadside radiation pattern and gain are achieved.Index Terms-Antenna array, dual-band antenna array, filter, microstrip antennas, multifunction aperture, patch antennas, WLAN.
