Increasing radiation power in half width microstrip leaky wave antenna by using slots technique

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