“…Hence, feeding the slot antenna from the center blocks a considerable portion of the miniaturized slot antenna [17]. There are other methods to feed the slot antenna with CPW lines, including an inductively or capacitively fed slot [18].…”

Abstract-With the virtual enforcement of the required boundary condition (BC) at the end of a slot antenna, the area occupied by the resonant antenna can be reduced. To achieve the required virtual BC, the two short circuits at the end of the resonant slot are replaced by some reactive BC, including inductive or capacitive loadings. The application of these loads is shown to reduce the size of the resonant slot antenna for a given resonant frequency without imposing any stringent condition on the impedance matching of the antenna. In this paper, a procedure for designing this class of slot antennas for any arbitrary size is presented. The procedure is based on an equivalent circuit model for the antenna and its feed structure. The corresponding equivalent circuit parameters are extracted using a full-wave forward model in conjunction with a genetic algorithm optimizer. These parameters are employed to find a proper matching network so that a perfect match to a 50 line is obtained. For a prototype slot antenna with approximate dimensions of 0 05 0 0 05 0 the impedance match is obtained, with a fairly high gain of 3 dBi, for a very small ground plane ( 0 20 0 ). Since there are neither polarization nor mismatch losses, the antenna efficiency is limited only by the dielectric and Ohmic losses.

“…In this paper, a new design of millimeter wave antenna inductively feeding technique with high efficiency and low cross-polarization is proposed. The idea of this feeding technique is inspired from the work reported in [7]. However, this technique has been used only as a radiating element and not as a feeding coupling technique.…”

“…The CPW has gained more and more popularity since it has many advantages over the microstrip-line, such as the lower radiation loss, less dispersion, and easier integration with the active and passive devices. Moreover, using apertures as radiating elements in the CPW-fed planar antenna arrays will make the structure uniplanar and facilitate the input impedance matching [5]. Thus, in this paper, we propose a novel in-line series-feed collinear slot array antenna fed by a CPW.…”
