Abstract
Design methods of the simple tap feed structures are clarified. It is shown that this. Tap feed can match very small input resistance of 1.2 Omega to 50 Omega coaxial cable. And through the designed example, achievement of high gain of 1.08 dBd in the low profile normal mode helical antenna is shown in the case of the metal proximity use.
