A Wideband Multibeam Planar Quasi-Yagi Array Antenna Based on Parasitic Pixel Strips
This letter presents a low-complexity parasitic pixel strip (PPS) structure for an array antenna to generate six radiations with flexible beam control. To realize multibeam operation, three groups of symmetrical strip-shaped pixels are integrated with the feed antenna, the connection state of which can be controlled by p-i-n diode. Leveraging the reconfigurable parasitic configuration, the coupling path of the antenna can be strategically manipulated, achieving the desired multibeam property. Thus, by utilizing the PPS structure in conjunction with a planar quasi-Yagi antenna, this single antenna can operate at four states with beam direction toward 40°, −40°, 0°, along with a dual-beam at ±45°, within the frequency range from 5.0 GHz to 5.6 GHz. Moreover, a prototype of a 1 × 2 array with the PPS structure is also fabricated to achieve six beams with a scan range of 40°, 20°, 0°, −20°, −40° and a dual beam at ±30°. Notably, only four p-i-n diodes are utilized to implement six radiations, verifying that this approach effectively minimizes the excessive use of switches and extends the variety of beams, which provides a low complexity method for multibeam array antenna without a complicated beamforming network. These antennas satisfy the benefits of wideband, planner structure, low structural complexity, low cost, and flexible beam control.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
