<p class="Default">The radiation power in the endfire is decreased while the main beam of half substrate integrated waveguide scan from broadside to endfire in a forward. The design of half-width microstrip leaky-wave antenna (HW-MLWA) has been presented in this work to increase the power radiation near endfire by using the slots technique in the radiation element. This slot leads to a decrease the cross-polarization. The proposed design comprises one element of HW-MLWA with repeated meandered square slots in the radiation element. One aspect of this antenna is generated by using a half substrate integrated waveguide with a full tapered feed line. The proposed antenna was terminated by load of 50 Ω, and feed on the other end of the antenna. Finally, the suggested design is simulated and acceptable results were found. The released gain is increased from 10.6 dBi to 12 dBi at 4.3 GHz. This design is suitable for unmanned aerial vehicle UAVs at C band application.</p>

Wireshark is easy for using as a packet inspection tool, in additional the feature of packets colorizing is easy for a various type of traffic. This paper exemplifies how Wireshark is used in networks as a tool. To clarify the effectiveness of malicious packet identification in any network, an experiment was conducted. Using the Wireshark program, testing was carried out in real time through experimentation and analysis. Inferences were drawn that clearly show Wireshark's capabilities as a tool in a powerful system for discovering the breach. The functionality of Wireshark is to analyze the network protocol and its open-source features for enabling the addition of likely tasks in the detecting devices were emphasized. Wireshark's skills for handling and interpreting packet data have been highlighted and the access control list (ACL) filtering has been the main application of Wireshark.
