Retrodirective Harmonic Tag Using Van-Atta Array [PDF]

In this paper, the concept of retrodirective harmonic tag using the Van-Atta array is proposed. Its effectiveness is evaluated through experiments using a 2-element patch antenna for each subset-antenna, where the 2nd harmonics was used for the uplink ...

A Reconfigurable Ultra-Wideband (UWB) Antenna with Single Band-Rejection [PDF]

, 2018
In this paper, a reconfigurable ultra-wideband (UWB) antenna with WLAN band-rejection is presented. The proposed antenna operates in the ultra-wideband frequency band from 2.99 – 10.82 GHz with band- rejection of 5.00 – 5.85 GHz.
