This paper presents a wideband Microstrip patch antenna with integrated circular slot for radio frequency energy harvesting. The antenna consists of circular slot and stubs with a coaxial feed. The proposed antenna consists of four symmetric gap. It is designed on FR4 lossy epoxy substrate material for 2.65GHz frequency allocated for Wi-max application. Circular slot are integrated inside a square patch of proposed antenna which helpsto increase the bandwidth of antenna.

In this paper a single fed microstrip patch ultra-wideband rectenna for harvesting ambient radio frequency energy is presented. The rectenna comprises of a rectangular shaped radiating patch operating at L band frequencies. The rectifier circuit is placed in the same plane of radiating patch to minimize the overall rectenna profile. The rectenna is modelled and are fabricated on low loss roger dielectric substrate. Measured results shows that the rectenna attains a maximum gain of 5 dB in the operating L band with maximum RF conversion efficiency of 81%. The rectenna designed is appropriate for harvesting wireless RF signals operating in L band.

AbstractIn this paper, a miniaturized microstrip patch antenna using a negative index metamaterial with modified split-ring resonator (SRR) unit cells is proposed for ultra-wideband (UWB) applications. The new design of metamaterial based microstrip patch antenna has been optimized to provide an improved bandwidth and multiple frequency operations. All the antenna performance parameters are presented in response-graphs. Also it is mentioned that the physical dimensions of the metamaterial based patch antenna are very small, which is convenient to modern communication. A 130 % bandwidth, covering the frequency band of 2.9–13.5 GHz, (for return loss less than or equal –10 dB) is achieved, which allow the antenna to operate in the Federal Communication Commission (FCC) band. In addition, the antenna has a good radiation pattern in the ultra-wide band spectrum, and it is nearly omnidirectional.

Abstract A Quick Response (QR) Code style antenna is presented. Such an antenna can provide two-level authentication, both optically through the current QR technology, plus a radio frequency (RF) signature from microstrip patch antenna designed from the QR signature using copper patterning. The antenna is designed through the pixilation of a patch antenna where conductor is present in the dark regions of the optical QR code. The QR based antenna design has a unique frequency and radiation signature and can be used for RF authentication of products. The design process for the pixilation is presented as well as fabrication and measured results of a QR code antenna design. The possibility of using a Genetic Algorithm to create a “library” of acceptable antenna results in accordance with the QR data it represents is also discussed.

In this paper, we study behavior of Ultra wideband antenna which is Rectangular Slotted Microstrip Patch Antenna. Then, the antenna operated in proximity of human arm model. Furthermore, the antenna is designed on a FR-4 substrate with dielectric constant of 4.3 and thickness 1.6 mm. This antenna simulated in CST Microwave Studio software. In order to test the antenna, an arm model was numerically modelled. The study shows properties and performances of antenna when it is placed in three situations which in free space, outside and inside of human arm model. The properties of UWB antenna in term of return loss, gain, directivity and radiation pattern in the three situations is simulated and discussed.
