## Abstract The phase centre of a dualβmode circular microstrip antenna is investigated when the fundamental TM~11~ and higher order TM~02~ modes are excited. It is shown that the location of the phase centre can be controlled by the excitation amplitude and phase of these modes. The problem is tre

β¦ Synopsis
We present an aperture-coupled microship antenna for mobile applications. The antenna is investigated eperimental(y and its measured impedance and radiation propetiies are verijied by a cavity model. A theory for an aperture-coupled microship antenna at higher-order modes is developed by application of the caviry model, and the characteristics at the TM1, mode are reported. A maximum bandwidth of about 8% is
achieved The investigations may be use@ for low-angle scanning applications using conical beams.

In this paper, the tilt of a feedline with regard to a slot is taken into account to impro¨e the ca¨ity model, and also to see the effect of this angle on the input impedance. In fact, the angle is introduced in the ¨oltage discontinuity of the slot on the feeding line. The computed results are comp
A hemispherical dielectric resonator antenna excited by a microstrip feedline through a narrow slot in a thick ground plane is studied theoretically and experimentally. A numerical method based on a combination of the spectral Green's function, modal Green's function, and the method of moment is use
In this paper, we present the characteristics of circular polarization of an elliptical microstrip patch fed by a coaxial probe through the method of moments in conjunction with the reaction integration method. After obtaining the general Green's function, the input impedance was calculated by super
