“…Figure 1 shows the configuration of the millimeter wave slot antenna with a tuning stub. Slot antennas have also been designed in the past using a microstrip feeding mechanism [18]. The design has been performed using Agilent's Momentum Electromagnetic Simulator, which predicts the performance of the membrane-supported antenna in terms of radiation pattern, antenna efficiency and input impedance.…”

Abstract-A low profile CPW fed millimeter wave rectangular slot antenna operating with a wideband; centered at 94 GHz has been designed, fabricated and tested on a 10 µm silicon diaphragm. To improve the bandwidth of the conventional slot antenna a C-shaped tuning stub has been incorporated. Measurement results show that the antenna operates from 75 to 105 GHz with a reflection coefficient better than −10 dB. At its resonant frequency the fabricated slot antennas have a reflection co-efficient ranging from −25 dB to −35 dB. The bandwidth of the antenna with a tuning stub was found to be over 30% at −10 dB. By using the slot antenna with a C-shaped tuning stub the bandwidth has been shown to improve, which could be used for several Millimeter wave applications.

“…Few researchers have proposed slot antennas using microstrip technology. In [2] the author has developed the thirteen element linear slot antenna array for the X band and forms the relation to compute the mutual coupling between the slots and E / H plane field. The major drawback of the slot antenna is a bidirectional radiation pattern.…”

A novel concept of SIW cavity-backed dual inverted edge curved L slots antenna array with the defective ground plane is proposed in this paper. A linearly placed six-element inverted dual L slots array antenna is designed separated by a distance of 0.55λ g to achieve high gain. Each pair of slots is separated by a column of the vias to form sub-cavities and those are fed individually. Defective ground structure (DGS) is introduced at the ground plane to manage the propagation of wave to the last slots in the array. The slots are enclosed by a SIW cavity of height 0.24λ g in a single substrate. A measured peak gain of 8 dBi is achieved at 14.29 GHz. The antenna shows a front-to-back ratio of 24.9 dB. The design is also compared with various aspects to show the advantages of each element introduced in the design. The validity of the design is proved by the good agreement between the simulated and measured results. This novel design can be used to achieve the performance requirement of a satellite antenna working in Ku band.

“…Since the early 90s, microstrip slotline has been extensively deployed for making microwave components such as antennas [4][5][6] and couplers [7,8]. In [9], it was found that an additional resonance could be excited by feeding a high-impedance stubline near to the slot edge, combining with its fundamental slot mode to provide broad bandwidth.…”

Abstract-For the first time, the higher-ordered modes of a stepped-impedance slotline resonator are closely combined for designing the broadband in-phase and out-of-phase power dividers. It was found that the output phases of the two modes can be easily reversed at the same time by changing the direction of their feeding currents. For this configuration, interestingly, a multifunctional power divider which is reconfigurable to produce either in-phase or out-of-phase signals can be easily designed from its passive counterparts by incorporating multiple RF diodes into the output feedlines, leading to significant cost saving and high compactness. The design procedure and equations of the power-dividing structures are discussed.
