Abstract

Electrically small shortened HF and VHF microstrip cylindrical antenna with a reduced antenna length are provided. The electrically small shortened HF and VHF microstrip cylindrical antennas are constructed with concentric, ceramic cylinders having copper coating that operate at low frequencies. The concentric, ceramic cylinders alternate with concentric copper layers in a corrugated alternating structure where certain copper layers function as the ground plane and others function as part of the radiating patch providing both a shortened antenna length and the ability to operate efficiently at low frequencies. It is now possible to provide a ten-fold size reduction with these antennas.
