Micro-strip antenna

Abstract

Abstract PURPOSE:To obtain input impedance characteristics over a wide band range with a simple structure by providing a parasitic conductor on the inner surface of a radome covering a radiation conductor. CONSTITUTION:Since a parasitic conductor 5 is fitted to the inner surface of a radome 7 with a bonding agent, etc., a dielectric holding body can be omitted and at the same time, the conductor 5 is faced to a radiation conductor 3 beyond an air layer or dielectric layer 4 and the conductor 5 can be made to have a circular shape. When the radiation conductor 3 is excited, the radiated field excites the parasitic conductor 5 provided on the inner surface of the radome 7 through the air layer or dielectric layer 4 and radio waves are radiated into the air. Therefore, an micro-strip antenna which can have wide-band impedance characteristics similar to those conventional antennas with a simple constitution can be obtained.
