Abstract
Antennas useable in all types of weather conditions are disclosed for use in various applications. The antenna is a flat array with either microstrip or slotted waveguide radiating elements. The radiating elements can be either transmitting or receiving elements for the array, or can be two arrays, each dedicated to one half of the transmission link. The array is covered with a radome to prevent water droplets, ice, or snow from forming on the antenna surface, thus allowing beam launching or beam reception at the antenna surface. The antennas can be used in a wide field of applications, including microsatellite communications links. Also disclosed is a microstrip, dual-band phased array antenna having a top dielectric including an antenna array patch directly coupled to a receive feed network and a lower dielectric having a transmit feed that is coupled to the antenna array patch through an intermediate metallization layer having coupling slots.
