“…In fact, different strategies are already proposed to reduce the size of the antenna array and make it multi or wide-use. Recently, the defected ground structure (DGS), defective microstrip structure (DMS) and electromagnetic bandgap structure (EBG) [22], [23] have received a lot of attention due to their ease, as well as the flexibility to be introduced in the designs of the structures. Several configurations of DGS have been exploited to miniaturize antenna or rather antenna array.…”

The requirement for applications operating at a variety of frequencies in a unified wireless device has greatly enhanced in recent years. For this purpose, multi-functional wireless components are essential. This paper presents a new design of a wideband circularly-polarized microstrip antenna array with defected ground structure (DGS). A previous design was introduced which cover the C-band at 5.8 GHz and operates in the industrial scientific medical (ISM) band for wireless communication applications. The proposed antenna has excellent performances which include good input impedance matching with a fed of the circular polarization at 5.8 GHz. The proposed design is validated and optimized by adding a new design of defected ground structure. This aperture geometry enables the antenna to operate in a wideband. The obtained results show that the modified antenna has a good performance in terms of return loss, bandwidth, gain and radiation pattern and demonstrate that the proposed antenna offers a good solution for multi-standard wireless communication applications.

“…Microstrip patch antennas are an attractive choice due to their light weight, low profile with conformability, flexibility of achieving CP radiation [3]. However, large microstrip arrays show low efficiency due to ohmic loss, dielectric loss and parasitic radiation in the feed network [3,4]. In contrast, waveguide-fed slot arrays can provide high gain along with desirable efficiency and bandwidth [5,6].…”

A wideband circularly polarized (CP) slot array with high radiation efficiency is proposed. The cavity-backed square slots are designed to achieve wideband CP radiation with a unidirectional pattern. The slotted waveguide is adopted to feed the array with high efficiency. The square slot, cavity and feeding slot in the waveguide can be viewed as a radiating element. A CP slot array can be conveniently designed as traditional waveguide slot arrays, once the element admittance characteristic is determined. A 1-by-8 CP array operating at 12.5 GHz has been developed. Measured impedance bandwidth of 6.9%, axial-ratio (AR) bandwidth of 8.8% and a gain of 15.4 dBi have been achieved. This array can be conveniently expanded to a larger wideband CP array with a higher gain, which is preferred for the specific satellite communication applications.
