“…In [35], using the concept of gap-coupling, the microstrip patch antenna is designed for 77 GHz millimeter band. In [36], authors have presented the novel configurations of compact and broadband coupled microstrip antennas (MSAs). Bandwidths of the proposed antennas are 5.4 − 6.1 times greater than the corresponding conventional MSAs.…”

In this paper, a technical review on gap-coupled microstrip antennas is presented. The gap-coupled microstrip antennas give a large bandwidth as compared to the conventional microstrip antennas. The method of bandwidth enhancement using gap-coupled microstrip antennas has been elaborated. The gap-coupled microstrip antennas also produce two resonances. The dual frequency operation of the gap-coupled microstrip antenna is also described. A research overview of gap-coupled microstrip antennas, challenges, types of gap-coupled microstrip antennas as well as numerical methods of calculating various parameters of the gap-coupled microstrip antennas are discussed in this paper.

Abstract-A synthesis procedure is developed in this paper for the design of N-step coplanar waveguide-to-microstrip transitions. An equivalent circuit approach is adopted to model the structure in terms of N cascaded ABCD matrices relative to the N coplanar waveguide sections forming the transition. A constrained optimization problem is formulated as the minimum finding of a proper functional to accurately determine the transition dimensions by imposing an upper bound to the return loss within a prescribed frequency band. An iterative Nstep procedure is developed to find the optimization problem solution. Numerical results on millimeter-wave transition configurations are provided to demonstrate the effectiveness of the proposed synthesis method. A back-to-back transition prototype with N = 3 sections is then fabricated and characterized in terms of measured S-parameters to experimentally demonstrate a return loss better than 10 dB in the frequency range from 1 GHz up to 40 GHz.

A printed CPW-fed monopole antenna with dual band-notched characteristics for UWB applications is presented in this paper. By etching both inverted elliptical split ring slots on the radiating patch dual band-notched characteristics are obtained a narrow bandwidth at 3.3-3.8 GHz for WiMAX (3.3-3.7 GHz) and for WLAN (5.725-5.825 GHz) operating bands are achieved. The physical structure of the proposed antenna is printed on the 28 mm × 34 mm × 1.6 mm size FR-4 dielectric substrate. The presented antenna has a wide impedance bandwidth of 2.89 to more than 14 GHz expect of two notch bands. The antenna operates for the entire UWB (3.1-10.6 GHz) range and gives omnidirectional radiation patterns and stable peak gain expect at the band-notched frequencies. The proposed antenna has a planar geometry which is a good choice for any portable UWB communication system applications.
