A Design of the Detection End Antenna with the Structure of Double Layers Printed Dipole

This paper examines a new measure of the detection end antenna model designed to the frequency-selective level,broadband electric-field probe.It is based on double layers printed dipole which overcomes the difficulties found in the prototype transfer-standard electric-field probe which put forward by NBS in 1986.The difficulty of fabracation is fallen and it realize the performance of the standard E-field probe using traditional single layer structure dipoles.It is much easier to fix the antenna.The main theme of the paper is to extend the utilization of the double layers printed antenna using the theory of resistively tapered dipole for broadband E-field probe's antenna.This double layeres printed dipole element allow a analysis of gain frequency response curve flat within 0-2.5dB from 11.8GHz to 15.2GHz,and obtain a stable isotropic response.
