This paper presents a multiband, metamaterial loaded microstrip patch antenna. Closed C-shaped slot has been used to miniaturize both mushroom type electromagnetic bandgap structures and microstrip antenna. Bandgap of microstrip antenna has been shifted to 5.5 GHz from 6.5 GHz using Closed C slot. This bandgap structure, when used as a substrate of patch antenna, results in multiband operation due...
A uniplanar-compact electromagnetic band-gap (UC-EBG) structure is implemented at 60 GHz on a conventional PTFE (polytetrafluoroethylene) substrate. The structure surrounds a stacked microstrip antenna with gridded parasitic patch. The UC-EBG implementation results in about 5 dB decrease in the antenna E-plane normalized radiation pattern for angles along the substrate. The measured antenna gain increase...
This paper describes the antenna performance enhancement by employing electromagnetic band gap (EBG) structures as the substrate of the antenna operating around 11 GHz, that suppress the surface waves and help the whole field to radiate by patch. Three different bandgap structures like mushroom EBG, partial substrate removal and grid EBG have been designed and investigated for their bandgap characteristics...
A new EBG structure is designed and introduced in this paper, and its radiation properties such as reflection phase and band gap area are presented. Also this new EBG structure is compared with a usual Mushroom-like EBG structure. Both of these EBG structures have a substrate with same size and same material. But the new EBG structure is designed with a new patch shape and also there is no connecting...
A method to enhance gain of a microstrip patch antenna is investigated by partially removing the substrate surrounding the patch. The partial substrate removal reduces the losses due to surface waves and dielectric substrate. The effects of substrate removal in different configurations on the gain of the antenna are studied numerically and validated experimentally. Compared to a conventional patch...
Microstrip Antennas (MSAs) consist of a metallic radiating patch on one side of thin dielectric substrate and other side is ground plane. Most important advantages of MSAs are low profile, light weight and compatibility with integrated circuit technology. MSAs are used in mobile communication, satellite communication, radar, direct broadcasting, global positioning systems and remote sensing. The major...
