Summary:
Magneto electric (ME) dipole antennas [1-3] are proposed for having wideband, stable gain and pattern across the entire passband. These antennas are simple in structure, ease of fabrication, and low cost. Some designs based on the concept of ME-dipole have suggested to be a dualpolarized antenna [4] for mobile communications, a circularly-polarized antenna [5] for satellite broadcast services, and a very wideband antenna [6] for WLAN systems, etc. All of the above mentioned [1-6] are only drawn the focus on microwave band applications. However, the recent trend of wireless communications is running to higher frequency like the instances of millimeter wave and THz frequency bands, so that the development on the antenna operating at very high frequency is popularly demanded. Among many types of millimeter wave antennas [7-8], they are expensive in manufacturing cost due to their very tiny size in radiating element and preciseness in feed mechanism. Some low-cost designs for millimeter wave antennas [9] are poor in narrow bandwidth or they do not have good radiating patterns [10] for the whole operating bandwidth. In this paper, we study and propose a new structure of millimeter wave antenna by introduction of ME-dipole fabricated on the microwave substrate. This proposed antenna is simple in the inherent architecture in the both of radiating element and feed line. The design yields advantages for wide impedance bandwidth, good directional radiation pattern across the passband and low fabrication cost.
