A large frequency interval dual-band high-gain slot array antenna based on SIW (substrate integrated waveguide) for simultaneous microwave and millimeter wave application is proposed in this paper. The designed antenna consists of 2 arrays working on 9.86 GHz ~ 10.2 GHz and 25.9 GHz ~ 39.53 GHz, which can meet demand on X- and Ka-band, respectively. Two substrates sandwiched between three layers of metal are employed, and all slots are located on the second metal layer.

Desktops and laptops can be maliciously exploited to violate privacy. In this paper, we consider the daily battle between the passive attacker who is targeting a specific user against a user that may be adversarial opponent. In this scenario, while the attacker tries to choose the best vector attack by surreptitiously monitoring the victim’s encrypted network traffic in order to identify user’s parameters such as the Operating System (OS), browser and apps. The user may use tools such as a Virtual Private Network (VPN) or even change protocols parameters to protect his/her privacy.

In this letter, a compact pattern reconfigurable filtering microstrip antenna is presented with broad bandwidth, good selectivity at the passband edge, and flat gain frequency response. The pattern reconfigurable filtering antenna has four resonant modes which can be adjusted independently, three of them are created by multi-mode resonator (MMR) and the other one is by radiator. The four resonant modes are well distributed in desired band and the resonant mode of radiator is located between the first two resonant modes of MMR.

In this paper, we present the Tree Exploration Discovery Protocol (TEDP), proving that shortest paths can be built at the same time that the topology information is gathered, without extra messages compared to LLDP.

An integration process for the fabrication of thin film bulk acoustic wave resonator (FBAR) above the CMOS IC is proposed. An adhesive-bonding-based film transfer technique is utilized to transfer high resistivity Si film onto a CMOS chip. Benzocyclobutene (BCB) is used as an adhesive film. It is a heat resistive polymer and processes of temperature up to 300 C are allowed on it. The CMOS is protected by BCB and thus is not damaged by plasma and chemical treatments.

The dataset is an extensive collection of labeled high-frequency Wi-Fi Radio Signal Strength (RSS) measurements corresponding to multiple hand gestures made near a smartphone under different spatial and data traffic scenarios. We open source the software code and an Android app (Winiff) to create this dataset, which is available at Github (https://github.com/mohaseeb/wisture). The dataset is created using an artificial traffic induction (between the phone and the access point) approach to enable useful and meaningful RSS value
