TL;DR: A novel design of an electromagnetic bandgap (EBG) structure based on the uniplanar compact EBG (UCEBG) concept is proposed in this paper, which is applied to enhance the performance of a single-element microstrip patch antenna and a two-element array conflguration.

TL;DR: In this paper, the authors used the lossy-drude model to reduce the Speciflc Absorption Rate (SAR) with ferrite sheet attachment and showed that the SAR averaging over 10gm was better than that for 1gm and SAR reduction of 57.75% is achieved for SAR 10gm.

TL;DR: A novel, low cost, and comprehensive microwave imaging system is presented for the detection of unwanted tumorous cells into the human breast by using AMC inspired CPW-fed antenna based microwave imaging, which can clearly detect the tumor inside the breast phantom.

TL;DR: Investigations show that the antenna designed with an inverse S-shape patch and connecting rectangular box in the microstrip line has a higher efficiency and gain compare to the conventional meander shape antenna, and the gain and efficiency can be improved through adjusting the rectangular box with applying parasitic element and the shaped ground.

TL;DR: In this article, the performance of a concentric ring reflectarray element backed either by a solid metal ground plane or a frequency-selective surface is compared, and the results show that the in-band reflection phase response of the two structures is similar; however, the periodic surface reduces the out-of-band reflectivity of the antenna by more than 4dB, thereby decreasing its RCS profile to these signals.
