Hybrid coupled shorted rectangular microstrip antennas
IEEE Antennas and Propagation Society International Symposium. 1999 Digest. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.99CH37010), 1999 Results for wide band and dual frequency operation using hybrid (gap and direct) coupling along the radiating and the non-radiating edges of two shorted rectangular microstrip antennas have been presented. Dual frequency operation has been obtained using compact shorted stacked rectangular microstrip antennas.

A hybrid adaptive antenna array [PDF]
IEEE Transactions on Wireless Communications, 2010 Owing to the excessive demand on signal processing and space constraint, a full digital implementation of a large adaptive antenna array at millimeter wave frequencies is very challenging. Targeted at long range high data rate point-to-point link in the 70/80 GHz bands, a novel hybrid adaptive antenna array which consists of analogue subarrays followed

Ultrafast Plasmonic Nanoantenna-ITO Hybrid Switches
International Journal of Optics, 2012 We present here a new type of device using nonlinear hybrid antenna-semiconductor (ITO) interaction. We observe a picosecond transient response from the antenna that cannot be explained by either pure ITO or antenna nonlinearities independently. We study

Hybrid optical antennas with photonic resistors
Optics Express, 2015 Hybrid optical antennas, comprising active materials placed in the gaps of plasmonic split-ring-resonators and nano-dimers, have been the subject of numerous recent investigations. Engineered coupling between the two plasmonic resonators is achieved by modulating the active material, enabling control over the near- and far-field electromagnetic ...
