Wide scanning phased array antenna design in Ka band

This paper presents a new antenna design for passive RFID tags operating at super high frequency band. The proposed antenna includes a cross-array of five elements supporting beam-scanning range over two perpendicular directions. The beam-scanning capability allows the tag to communicate over longer distances without demanding extra power. A matching network between antenna elements and front-end circuitry has also been designed to eliminate phase shift. 3D full-wave electromagnetic simulation results using HFSS CAD tool indicate that the proposed antenna supports 10 dB gain and beam-scanning of more than 180 o over two planes which can be exploited to provide location positioning services.

An 8 x 4 microstrip antenna array operating within 24 GHz frequency range has been shown. The presented antenna features two beams: a broadside beam and a dual beam. It allows for detection of targets in two different ranges and at two different angular positions. Additionally, the antenna can be used for the direction finding. The proposed antenna array uses 'through-element' series feeding technique for dissipation losses reduction as well as the stacked laminate structure to separate the radiating elements and the feeding network, which allows for achieving satisfactory radiation patterns in a wide frequency range.Index terms-multibeam antennas; multi-layer antennas; microstrip antenna arrays.

“…With the development of microwave technology, antennas with the performances of wide operation band and broad beamwidth are becoming more demanding in intelligence transportation system, navigation and secure communication applications [1]- [2].In some occasions, surface-wave antennas such as slot antennas, have been widely used due to the attractive features of low side-lobe and wideband design [3]. However, they still have the obstacles of producing unstable broad beamwidth pattern with frequency.…”

A novel coplanar waveguide fed printed rectangular slot antenna is proposed in this paper, which consists of a substrate layer of the CPW-fed rectangular slot antenna, a composite cavity, and a SMA connector with the vertical transition structure. The simulated results indicate that the antenna has the 10dB impedance bandwidth of 49%, the 3-dB beamwidth of exceeding 107° in E-plane, the gain of 6dBi, and with a compact size.
