With a 2-element array antenna consisting of a radiator and a reflector, the gain variation is small over an octave frequency range (the absolute gain is as high as 9.6 dB) and the impedance is also wideband. A high-gain, wideband operation will be achieved with a small number of ...
The geometry of the Yagi-Uda array: The second dipole in the Yagi-Uda array is the only driven element with applied input/output source feed, all the others interact by mutual coupling since receive and reradiate electromagnetic energy; they act as parasitic elements by induced current. It is...
A surface wave driven plasma Yagi-Uda monopole array composed of several surface wave driven plasma monopole elements is proposed and studied with finite difference time domain simulation in this work. By varying the excitation power of plasma monopoles, a reconfigurable antenna is obtained for ...

Measuring the optical properties of the structure reveals that impinging light on the array is efficiently absorbed on the subwavelength scale because of the high directivity. Moreover, we show in simulations that combining the array with suitable feeding circuits gives rise to the prospect of beam ...
