HIGH GAIN-AREA-PRODUCT ANTENNA DESIGN

摘要

A high gain-area-product antenna using a dual mode feel element is designed to provide substantially uniform gain coverage over an angular region. The primary pattern (6) emitted at the antenna feed (2) is modified to make the H-plane distribution approximate the E-plane distribution (3). Both the main lobe and side lobes of the primary pattern are projected onto the reflector (4) in order to establish a secondary projected pattern (8) which approaches an ideal sector beam.
