A novel, potential and efficient microwave direct contact hyperthermia applicator referred to as water-loaded box-horn for therapeutic heating of bio-medium is designed and developed at 915 and 2450 MHz. Also, theoretical expressions for fields in bio-medium as produced by a direct contact box-horn applicator have been derived using plane wave spectral technique. The box-horn is a special type ...

In this study, a high-gain and dual-polarized Quad Ridged Horn Antenna (QRHA) is proposed designed to be used in Obstacle Penetrating Imaging Radar (OPIR) applications. The quad ridged design developed then optimized by using the antenna simulator software; CST Microwave Studio. parameters including center frequency, frequency bandwidth radiation pattern beam width are considered based on requi...
