A novel kind of composite patch antenna is proposed, in which the mushroom-like electromagnetic band-gap (EBG) structure is integrated onto the conventional patch. Due to the high impedance property of the EBG structure, the scattering fields from EBG structure and the rest of antenna can be out of phase and cancel each other. The composite patch antenna exhibits a natural low in-band radar cross...
Radiation and scattering properties are two important factors of the antenna, especially for the antenna used in military system. In this paper, the radiation and scattering properties of a modified microstrip antenna with slots in the ground plane is studied. The backscattering and bi-static scattering properties both in-band and out-band of the antenna are analyzed. The results of this antenna are...
For traditional differential fed microstrip patch antenna, the phase difference between the two excitation ports is set to 180°. In this paper, the radiation and scattering characteristics of differential microstrip antenna fed by phase difference out of 180° are studied. The variations of the co-polarization and cross-polarization radiations of the antenna are analyzed, and the bi-static and mono-static...
