Abstract :
A novel coaxial slot antenna is proposed for satellite mobile communications. It uses five circumferential slots with optimised positions to achieve an upward-skewed main-beam for satellite tracking. The radiation pattern and gain and return loss of the slot antenna are discussed. The antenna has the advantages of high gain, high efficiency, low-cost and ease of fabrication
