A new antenna with both frequency and polarization reconfigurability is presented. The antenna consists of a square microstrip patch with a single probe feed located along the diagonal line. The center of each edge of the patch is connected to a shorting post via a p-i-n diode for polarization switching and two varactor diodes for frequency tuning. By switching between the different states of the...
A new millimeter-wave frequency reconfigurable quasi-Yagi antenna is presented. The quasi-Yagi antenna is printed on a quartz substrate integrated with RF MEMS switches. It consists of one driven dipole, two dipole directors, and one truncated ground plane as reflector. By controlling the actuation of the RF MEMS loaded on the driven and director dipole elements, the antenna operation frequency is...
A RF MEMS integrated frequency reconfigurable quasi-Yagi folded dipole antenna is presented. The operating frequencies of the antenna are interchangeable between the millimeter wave WPAN band (57–66 GHz) and E-band (71–86 GHz). This is achieved by electronically tuning the effective electrical length of the folded dipole driver and the director element by employing RF MEMS switches. Simulation results...
