Active Phase Conjugation with Multiple Antenna Array Element

In this paper we analyze the temporal and spatial compression characteristics of retrodirective antenna systems wherein active phase conjugation (APC) is deployed. It is shown that under the active phase conjugation Hermitian channel matrix properties result and these lead to opportunities for both temporal and spatial signal compression. The effects of additive channel noise, as well as compre...

Phased array antenna using MEMS phase shifter

This article presents a phased array antenna employing MEMS phase shifter. The proposed phased array antenna consists of eight square patch antennas operating at 10.4 GHz with a bandwidth of 400 MHz. Feed line for each patch passes through a MEMS phase shifter realized by a series of bridges above the transmission line. The distance between the bridge and the transmission line underneath it is ...

Planar Active Rectrodirective Array With Subharmonic Phase Conjugation Mixers

A planar active retrodirective four-element array with subharmonic phase conjugation mixers based on anti-parallel diode pairs (APDPs) is proposed. As compared to previous phase conjugation mixers using twice RF frequency for LO frequency, the proposed conjugation mixers need only half RF frequency so that it can be easily applied for millimeter-wave applications. Receive, transmitting, local o...

A High Frequency Phase Conjugation Array

A phase conjugation array (time-reversal mirror) time reverses the incident signal and precisely returns it to its original source location. A high frequency (~3.5 kHz) phase conjugation array (HFPCA) has been designed, fabricated, and deployed at sea in two experiments (July 1999 and May/June 2000) conducted jointly with the NATO SACLANT Undersea Research Centre. The HFPCA consists of 29 sourc...

Design and Fabrication of Plasma Array Antenna with Beam Forming

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...
