“…The CP pattern of a proposed circular disc patch antenna has been applied and designed by a truncated corner structure of a ground plane [4,5] with 45° inclined slots [5], two rec-tangular grooves on the circular disc patch [6] and an asymmetric gap at the feeding structure. Sections and present a theoretical analysis of the frequency response characteristics for the NLJD system and a novel design for wideband circular patch antenna, respectively.…”

“…Truncating the corner of the ground plane by 2.282 mm created a strong electric current flow that generated the CP. One theoretical approach to improve the axial ratio of the CP antenna was to cut a corner of square patch [4,5]. The CP was radiated by the degree and length of the inclined slot, and by the position and size of the groove.…”

This paper proposes a theoretical analysis of hidden device detection and a design of multiband circular polarization patch array antenna for non-linear junction detector system application. A good axial ratio of circular polarization patch antenna is realized by a new approach that employs inclined slots, two rectangular grooves and a truncated ground for the conventional antenna. A good axial ratio of the 1.5 dB lower is measured by having an asymmetric gap distance between the ground planes of the coplanar waveguide feeding structure. The common ground plane of the linear array has an optimum trapezoidal slot array to reduce the mutual coupling without increasing the distance between the radiators. The higher gain of about 1 dBi is realized by using the novel common ground structure. The measured return loss, gain, and axial ratio of the proposed single radiator, as well as the proposed array antennas, showed a good agreement with the simulated results.

“…Pang et al (2000) [17] introduced four CP cylindrical DRAs with cross-slot coupling of unequal slot lengths and a sequentially rotated microstrip feed which demonstrated that left-hand CP (LHCP) could be realized. An array based on geometrically modified rectangular DRAs was also demonstrated by Haneishi and Takazawa (1985) [18]. The 16 element array with paired units was designed to operate at X-band frequencies.…”

Abstract-This paper presents a design of circularly polarized dielectric resonator antenna (DRA) array. The dielectric resonators (DRs) were excited by rectangular aperture coupling slots feed with a linear microstrip. The slot positions were determined based on the characteristic of standing wave ratio over a short ended microstrip to deliver the maximum amount of coupling power to the DRs, in order to improve the array gain Each DR element was rotated 45 • with respect to the sides of the exciting slot to generate circular polarization pattern. The DRA array was modeled and simulated as a parallel RLC input impedance component using Agilent (ADS) software, since that will ensure the resonant frequency of the antenna as primary design step before simulating in (CST) software and doing the measurements. The results of the return loss, gain radiation and pattern axial ratio are shown. The gain of the proposed array in X band was about 8.5 dBi, while the 3 dB axial ratio bandwidth started from 8.14 to 8.24 GHz. The impedance bandwidths started from 8.14 GHz to 8.26 GHz. The proposed DRA exhibited an enhancement of the gain in comparison to a single pellet DRA. The size of the whole antenna structure is about 40 mm × 50 mm and can potentially be used in wireless systems.
