Abstract
A new antenna concept is proposed to improve and stabilize performance at the talk position of cellular telephones. Constant vertical average gain which is independent of its tilting angle and suppressed radiation toward an operator side can be realized by loop type antennas with uniform current distribution. The proposed square antenna of 0.54 λ circumference length with distributed capacitances is measured. Predictable results are obtained.
