Síntesis eficiente y directa de antenas leaky-wave en tecnología half-width microstrip para aplicaciones de RADAR monopulso escaneado en frecuencia

Abstract

[ENG] We propose a synthesis technique for half-width microstrip leaky-wave antennas (HWM LWAs) producing frequency-scanned monopulse patterns with two channels. The election of the substrate thickness and dielectric constant is of key importance to obtain the desired angular scanning in the prescribed frequency band, and with high radiation efficiency. Using the two far advertising channels of Bluetooth Low Energy (BLE) protocol in the 2.45 GHz band, we demonstrate that wide and narrow scanning designs can be directly obtained with the proposed approach, while dispensing from any numerical optimization. It is examined how different dielectric laminates and antenna sizes are convenient for each design.
