safety, and efficiency.V2V, or vehicle-to-vehicle Vehicles may communicate directly with one another and share information about their position, speed, and direction thanks to WLAN. This aids in managing traffic and preventing collisions. Vehicle-to-infrastructure (V2I) Automobiles and roadside units with WLAN capabilities may converse. Drivers may receive real-time traffic updates, light timings, and other important information via this interaction. Real-time traffic data gathering and distribution are supported by WLAN networks. Traffic signal optimization, congestion control, and dynamic route assistance for vehicles may all be accomplished with the use of this data. Car Radar Systems: Preventing Collisions Road safety can be improved by vehicle radar systems that operate at 25.6 GHz, which can identify possible collisions and promptly alert drivers to them. Control of Traffic Signals for Infrastructure Communication To ease congestion and boost traffic efficiency, 25.6 GHz sensors may dynamically modify signal timings while keeping an eye on traffic flow. This work presents an effective microstrip filter operating in the 25.6 GHz frequency range. Reduce insertion loss to maintain the integrity of the signal. To enhance the properties of signal reflection, optimize return loss. Antennas and filters are essential parts of ultrawideband wireless communication equipment. Modern microstrip antennas have to be small to fit tiny, portable devices. Microstrip antennas are especially well-suited for UWB applications because of their lightweight design, low profile, affordability, and ease of manufacturing. Planar antennas come in a variety of forms and varieties, and a wealth of documentation demonstrates their basic importance to UWB technology. The filter antenna is designed to function at a center frequency of 25.6 GHz. To suppress undesired signals, a bandpass filter with notch band characteristics is needed to overcome this issue. However, to minimize insertion losses and system space, combining the band-pass filter and antenna into a single module is growing in popularity. Thus, certain filtering antennas It has been stated that filters have frequency responses such as to produce band-notch features, the Microstrip antenna is liberally combined with diffractive resonators, open stubs, parasitic strips, shorting wires, and multi-stub feeds [2].
shaped wide-band planar filter-antenna design. Additionally, the impact of the type of dielectric material on the design's properties is examined and discussed. A monopole microstrip antenna cascaded with an E-shaped planar band-pass filter (BPF) forms the filter-antenna construction. This paper proposes a microstrip patch filtering antenna with a band-notched characteristic. The microstrip patch antenna has a bandwidth of 500 MHz The Centre frequency is 25.6GHz. The filter-antenna design is simulated and optimized using HFSSv24 software. It is measured using a Rogers TMM 10i (tm) The substrate used has a height of 1.28 mm, a dielectric constant of 9.8, and a loss tangent of 0.0020. The structure is printed on a compact size of 29.28mmx16.5mmx1.28mm. A good agreement is obtained between the simulation and measurement performance.

1. INTRODUCTION The world is shifting toward automation these days. Any nation's transportation network is its foundation. Transportation networks contribute to national prosperity. Thus, many antenna types that can regularly receive, send, or reply to signals are needed for an intelligent transportation system. Therefore, a multiband antenna that simultaneously receives various resonant frequencies is needed. Therefore, a new filter is needed to get the necessary resonance frequency. An essential part of creating and executing Intelligent Transportation Systems (ITS) is Wireless Local Area Networks (WLANs). The use of intelligent transportation systems (ITS) in transportation has several advantages, such as the development of new traffic models, the alleviation of congestion, and increased safety. ITS depends on a multitude of data sources, including voluntary data sharing by users and a variety of traffic and infrastructure sensors, to function well. Certain wellknown ITS apps, like as Waze and Google Traffic, are developed by businesses that don't make it obvious how they get this data from users [1]. ITS seeks to integrate cutting-edge communication technology into transportation networks to increase their sustainability,
