In this letter, a resonant slot array antenna using a compact partial H-plane waveguide is proposed. To design the antenna, the conductance value of a longitudinal shunt slot on the partial H-plane waveguide is numerically estimated using a commercial electromagnetic (EM) simulator and the analytic conductance equation. The partial H-plane slot array antenna behaves as a resonant 1-D structure with...
In this paper, a resonant slot array antenna of partial H-plane waveguide using inclined sidewall slots is proposed. The sidewall slots without edged sections in broad wall can be spaced by half a guided wavelength because the slots are embodied alternately in two sidewalls separated by a metal vane of partial H-plane waveguide having a phase difference of 180deg. To design the array antenna, the...
In this paper, the compact slot array antenna using partial H-plane is presented. The design antenna has one quarter cross section compared with that of conventional waveguide slot antenna. To design the antenna, the numerical design method is described and the slot array antenna is designed in S-band. The design results confirm that proposed antenna satisfy the array antenna performance in spite...
A MIMO antenna system is a well-known technique to enhance the performance of wireless communication systems. In order to create a MIMO antenna system on wireless handy device, two or more antenna elements could be placed in very small space. Thus, in case of a MIMO antenna in mobile handy terminal, the mutual coupling including radiation pattern coupling between closely arrayed antenna elements causes...
A novel internal antenna of compact 2-channel MIMO for handy terminal is presented for WiBro(Wireless Broadband Internet) which operating at 2.35 GHz band. The proposed antenna is designed for minimum space occupation on PCB board of a mobile device so that the circuit design of a mobile device is convenient. We investigated for the reduction of mutual coupling between antenna elements. To decrease...
This paper describes a novel method for suppressing mutual coupling between antenna elements for application in MIMO antenna design. To suppress mutual coupling, several parasitic elements were employed in the proposed MIMO array antennas. Due to the effect of these parasitic elements, mutual coupling is markedly reduced. The proposed method shows that the improvement of mutual coupling is at least...
