Волноводные конструкции приобрели популярность благодаря широкому применению в радиолокационных системах кораблей и самолетов Военно-морского флота. Волноводные модели обеспечивают высокую вероятность обнаружения мелких целей и снижают вероятность обнаружения ложных целей. Существует большое число исследований по широкой стенке щелевого волновода. Исследования, касающиеся узкой стенки волновода, известны много меньше. В работе предложена краевая волноводная щелевая антенная решетка на основе полукруглого конца наклонных щелевых излучающих волноводов. Длина наклонной прорези расширена до прилегающей широкой стенки полукруглой вырезки. Увеличенная длина повышает резонансную длину. Таким образом достигается более высокое усиление. Полукруглая вырезка в конце щели уменьшает составляющую кросс-поляризации, поэтому получаемый уровень боковых лепестков низкий. Проанализирован и спроектирован узкостенный наклонный щелевой волновод для работы в Х-диапазоне. Излучающие щели выполнены и поочередно повернуты на уширенной верхней пластине с полукруглой врезкой в соседние стенки. Этот метод позволяет удалять радиальную составляющую распространяющейся волны и добавляет осевую составляющую распространяющейся волны. Полукруглая нарезка увеличивает резонансную длину и увеличивает коэффициент усиления антенны. Разработанная волноводная структура обеспечивает высокий коэффициент усиления, а кроссполяризационная составляющая сведена к минимуму. В результате высокочастотного программного моделирования (High frequency Software Simulation, HFSS) получено усиление 26 дБ, уровень боковых лепестков составил около 20 дБ. Исследование реальной конструкция модели обеспечило усиление 24,5 дБ, измеренное на векторном анализаторе цепей (Vector Network Analyzer, VNA) при сохранении минимального уровня боковых лепестков.

Waveguide structures have got popularity because of its extensive application in radar system of naval ships and aircrafts. Waveguide models provide high probability of small target detection and reduce rate of false target detection. There are a large number of studies on the waveguide slotted in the wide wall. Researches concerning the narrow wall of the waveguide are much less known. An edge slotted waveguide antenna array based on semicircular end of inclined slots radiating waveguide is proposed. Length of the inclined slot is extended to the adjacent broad wall with semicircular cutting. This extended length increases the resonant length and hence higher gain is obtained. Semicircular cutting at the end of the slot reduces cross-polarization component hence side lobe level obtained are low. Narrow wall inclined slotted waveguide is analyzed and designed to operate in X-band. The radiating slots are etched and rotated alternatively on the broadened top plate with semicircular cutting into the adjacent walls. This technique deletes the radial component of the propagating wave and adds the axial component of the propagating wave. Semicircular cutting increases the resonant length and enhances the gain of the antenna. Designed waveguide structure provides high gain, and cross-polarization component is minimized. Gain of 26 dB is obtained from the simulation results obtained in HFSS (High frequency Software Simulation) and side lobe level obtained is around 20 dB while hardware design provides the gain of 24.5 dB measured on VNA (Vector Network Analyzer) keeping the side lobe level minimum.
