The shape and size of the slot, as well as the driving frequency, determine the radiation pattern. Often the radio waves are provided by a waveguide, and the antenna consists of slots in the waveguide.

Switched-Beam Slot Antenna over Electromagnetic Band-Gap ... Abstract. This paper presents the switched-beam slot antenna over the electromagnetic band-gap (EBG) reflector. This antenna is composed of two slot elements fed with phase difference and the EBG reflector, which is applied in order to realize the low profile structure. A SYSTEMATIC STUDY ON THE PERFORMANCE ENHANCEMENT OF ... Electromagnetic band gap (EBG) structures that are engineered to achieve desired transmission and reflection characteristics in specific frequency bands, have long been actively studied in the microwave regime for a wide variety of applications. They have also been used as superstrates for directivity enhancement of antennas as well as ABSTRACT Title of Thesis: COUPLING REDUCTION USING ...

Wideband slotted patch antennas using ebg structures

Electromagnetic Band Gap (EBG) circularly polarized slot-patch antenna in multilayered configuration. The operating frequency band can be controlled via the disk radius and adjusting the slit lengths. An arrangement combining the circular slot-patch antenna design and feeding sources included are considered is necessary.
