A method of ‘mode shifting’ is presented for realisation of triple-mode and dual-mode filters, in which the resonant frequency of one mode is shifted near to the resonant frequency of another mode using a perturbation. To ...

In this paper, a new leaky wave antenna (LWA) is introduced. The proposed antenna radiates through a dielectric aperture created by half mode substrate integrated waveguide (HMSIW) technique. A sample antenna is designed and simulated and its...

In this paper, a low profile single fed cavity backed slot antenna producing both linear and circular polarizations at two different frequency is presented using a halved dual mode cavity. The proposed antenna has a planar ...

In this paper, half mode substrate integrated waveguide (HMSIW) technique is introduced to realize a single fed low profile circular polarized cavity backed antenna for the first time. The proposed antenna is compact and is light in weight. Other...

In this paper, a new leaky wave antenna (LWA) is introducedو, which radiates through a dielectric aperture created by an half mode substrate integrated waveguide (HMSIW) technique. The proposed antenna is designed and numerically investigated using...

gain and radiation efficiency of this antenna are 8.33 GHz, 1.9%, 7.3 dBi and 94%, respectively. The second antenna which has a half mode substrate integrated waveguide (HMSIW) structure operates at the zeroth order resonance mode of the resonator. Its...

In this paper, two single fed low-profile cavity-backed

planar slot antennas for circular polarization (CP) applications

are first introduced by half mode substrate integrated waveguide

(HMSIW) technique. One of the structures...
