摘要：A low-profile monopole antenna with height below is proposed. The antenna is based on a square substrate-integrated
cavity radiating through apertures in its four side
walls. This effectively creates a small square loop of magnetic currents,
which radiates omnidirectionally as an electric monopole. The antenna cavity has a side length of less than and
thus resonates in the monomode region, in a fundamental mode. This means that the structure is robust in terms of feeding
and manufacturing tolerances, as no parasitic modes can be
excited. The designs of the cavity and the feed are introduced in
detail. The measurement results from a manufactured prototype
operating at 5.9 GHz show good agreement with simulations and
validate the proposed approach.
