Integrated radiation antenna of L-band magnetically insulated transmission line oscillator

According to the requirement of miniaturization, a kind of radiation antenna model integrated with mode converter for the compact L-band magnetically insulated transmission line oscillator(MILO) is put forward. The model uses dielectric and metal board for phase shift. It can greatly shorten the physical length of the mode converter. Based on this model, an integrated radiation antenna is investigated. The radiation antenna is designed and optimized by numerical calculation. The antenna’s characteristics such as far-field patterns, gains and physical length are also obtained.
