Beam and Frequency Agility Enhancement of a Microstrip Antenna through the Use of Metamaterials

International audienceThis paper presents a planar antenna making use of metamaterial technology in order to introduce simultaneous beam and frequency agilities within the system. A microstrip patch antenna is inserted in a Fabry-Pérot cavity made of a reflective surface on one side, and a semi-reflective surface on the other side, which permits the controlled radiation of the electromagnetic wav

AN ADAPTIVE MULTI-STANDARD ANTENNA FOR BEAMFORMING IN ADVANCED CELLULAR RADIO NETWORKS

International audienceThis paper presents a microstrip antenna, whose impedance is matched to work under multi-standard operation, and which provides the ability to steer the radiation pattern in the angular direction of interest. The proposed antenna structure is suitable for advanced cellular radio networks which implement beam forming techniques

Patch Antenna Bandwidth Enhancement through the Use of Metamaterials

ISBN: 978-1-4244-2936-3International audienceThis paper presents how Metamaterials can be used to enhance Antenna Bandwidth. To this purpose, a particular Metamaterial cell is introduced for which its design parameters are detailed. This cell is then used to enhance the performances of a microstrip antenna which can be found in communication systems. Index Terms--Metamaterials, LHM, artificial medium, microstrip antenna, frequency Bandwidth enhancement
