Analysis of an Electromagnetically Coupled Microstrip Ring Antenna Using an Extended Feedline

Abstract

A new method for the computation of input impedance of an annular ring microstrip antenna, fed electromagnetically by a microstrip line, and operating in its fundamental mode is presented. The method based on cavity model in conjunction with circuit theory is compared with simulation (IE3D TM ) and measurement based results. It is shown that this method of computation leads to accurate prediction of impedance for such structures with minimum of computational complexity, thereby making it an attractive tool for accurate and quick design estimate for many applications.

Resonance in Microstrip Ring Resonator with Uniaxially Anisotropic Substrate and Superstrate Layers

“…In later studies, new designs of annular ring microstrip structure are presented [4][5][6][7][8]. Anisotropic materials have also been considered in the annular ring structure in later studies [9][10][11].…”

Numerical and Experimental Analysis of Emi-Induced Noise in Rc Phase Shift Oscillator

“…The literature contains a large number of studies on the mitigation of EMI effects [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. For example, in [2], a method was proposed for detecting EMI-induced errors in radio frequency integrated circuit (RFIC) autotest-equipment (ATE) and for recovering these errors via a retest procedure.…”

Analysis of Annular Ring Microstrip Patch on Uniaxial Medium via Hankel Transform Domain Immittance Approach

“…These structures are also designed using uniaxially anisotropic materials and analyzed in spectral domain [14,17,18]. In some recent studies, new designs of annular ring microstrip structure for different purposes are also presented [20,21].…”
