Microwave holograms and microwave reconstruction

Electronics Letters, 1969
Microwave holographic reconstruction of the metal objects inside a purse was achieved by a nonscanning method. A microwave field was used for both constructing and reconstructing the holographic image. The visualisation of the microwave field was performed by both Polaroid and liquid-crystal techniques. The frequency used was 34.26GHz.

INNOVATIVE ASPECTS REGARDING UHF WAVES USED IN TEXTILE FUNCTIONALIZATION [PDF]

Annals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2018
This paper we present several innovative aspects regarding the UHF (ultra high frequency) microwaves used in textile functionalization for obtain a dielectric surface. The UHF microwaves (MW) are in the range 300 MHz÷3 GHz. In general, the microwaves are

Triband Omnidirectional Circularly Polarized Dielectric Resonator Antenna with Top-Loaded Alford Loop

International Journal of Antennas and Propagation, 2014
A triband omnidirectional circularly polarized dielectric resonator antenna with a top-loaded modified Alford loop for GSM, WLAN, and WiMAX applications is proposed. Fed by an axial probe, the DRA (dielectric resonator antenna) radiates like a vertically
