摘要：
A small slot-loaded patch antenna design developed for receiving both L1 and L2 bands GPS signals is discussed. The dual band coverage is achieved by using a patch mode at L2 band and a slot mode at L1 band. High dielectric material and meandered slot line are employed to reduce the antenna size down to 25.4 mm in diameter. The RHCP is achieved by combining two orthogonal modes via a small 0 degrees-90 degrees hybrid chip. Both patch and slot modes share a single proximity probe conveniently located on the side of the antenna (Fig. 1). This paper discusses about the design procedure as well as simulated antenna performance.
