A Wideband Slot Antenna with Folded Parasitic Line for ... sented antenna with folded parasitic line. It composes of a rectangular slot and a rectangular patch stub to perform wideband operation. In addition, the folded parasitic line, as depicted in Fig. 1(b), is placed on the surrounding of the rectangular patch stub to create a notched band for pre-venting unwanted frequency. Also, the rectangular patch Slot Line Fed Uniplanar Antenna for 2.4/5.8 GHz WLA N ... Slot Line Fed Uniplanar Antenna for 2.4/5.8 GHz WLA N ...

Design of Slot Antenna for Wideband Applications - ERNET antenna is from 2.69 to 10.24 GHz, I. INTRODUCTION Microstrip antennas can be divided into two basic types by structure, namely microstrip patch antenna and microstrip slot antenna. The slot antennas can be fed by microstrip line, slot line and CPW. In this paper, we presented the design of slot antenna fed by microstrip line. The designed Compact Rectangular Slot Patch Antenna for Dual Frequency ...

A Dual-Band Slot-Embedded Microstrip Antenna for Dual PDF | In this study, a new slot embedded microstrip antenna for dual-band dual-polarization operation is proposed. The antenna comprises a single layer structure with a square radiating patch Maximizing Gain of a Compact UWB Tapered Slot Antenna In order to develop and test a tapered slot antenna using the optimum value of B, it is preferred to alter the feeding structure of the antenna so that a microstrip feeder can be used instead of the slot line. It is well known that the microstrip line is the most common form of printed transmission line used for feeding a tapered slot antenna TAPERED MEANDER SLOT AND COPLANAR SLOT ANTENNA FOR DUAL AND ... A compact meander-type slot antenna with 56% size reduction has been reported in [3] in which non-uniform slot line widths give rise to lower operating frequency of the antenna. In this paper we show that a dual-frequency operation is achieved by using a tapered meander slot antenna with a short-ended microstrip line feed. The

Ring slot antenna. The ring slot antenna is known to have a symmetrical linear polarized antenna beam pattern [3], [4]. It is a compact antenna surrounded by a ground plane. This gives more flexibility to place all strip line elements very close to antenna itself. This antenna doesn't need a blocking capacitor if the central part is made in the ... A Review of Aperture Coupled Microstrip Antennas: History ... printed slot antennas fed with microstrip lines [6], but the bidirectionality of the radiating element was unacceptable. At some point in the summer of 1984 we arrived at the idea of combining these two geometries, using a slot or aperture to couple a microstrip feed line to a resonant microstrip patch antenna. Basic Antenna Theory - Wireless
