HIGH GAIN STEERABLE PHASED-ARRAY ANTENNA WITH SELECTABLE CHARACTERISTICS

摘要

A high gain, phased array antenna includes a conducting sheet having a number of one or more slots defined therein. For each slot, an electrical microstrip feed line is electronically coupled with a corresponding slot to form a magnetically-coupled LC resonance element. A main feed line couples with the one or more microstrip feed lines. A specific azimuth pattern, antenna frequency, and/or beam direction is/are selectable in accordance with specific structural or electrical characteristics of the antenna.
