This paper presents a new type of hybrid antenna geometry which can operate over triple bands. It consists of a U-shaped printed antenna and a cylindrical dielectric resonator antenna (CDRA) along with a ground plane which contains T-shaped slot. The proposed antenna operates over frequency ranges 5.75-6.56 GHz, 9.46 -12.7 GHz and 14.29-16.13 GHz and provides peak gain about 7.3 dBi. Different modes of CDRA like HEM11δ, TM01δ-like, HEM12δ and HEM21δare being excited. The proposed antenna can be used as an electromagnetic sensor for C, X and Ku band applications.

ABSTRACT In this paper, a compact defected ground mushroom electromagnetic bandgap (DG-MEBG) structure is presented. Compactness is achieved by employing a DG in the conventional MEBG. DG-MEBG exhibits a low pass transmission response with a cut-off frequency of 4.2 GHz and wide stop band up to 17 GHz as against a cut-off frequency of 10.4 GHz observed in a conventional MEBG. Thus the proposed DG-MEBG is 60% compact in comparison with a conventional MEBG structure. The measured results show a very good agreement with the simulated ones.

A polarization-insensitive dual-band artificial magnetic conductor (AMC) structure is designed and experimentally verified. It consists of a planar array of annular ring-slot loaded rectangular patches. Details of the proposed structure and origin of the two bands is discussed. Through simulations and measurements, it is shown that the structure is insensitive to polarization of the incident wave. The tuning of the higher AMC band is demonstrated by varying the capacitance of the annular slot through its width variation. The designed AMC is used as a reflector for a wideband monopole patch antenna. It is shown experimentally at the antenna frequencies in the AMC band that the gain of the antenna improves by almost 10 dB and front-to-back ratio is improved by 15 dB.
