摘要：

A 2.45-GHz electrically small slot antenna (lambda(0)/35 x lambda(0)/35, 3.5 x 3.5 mm(2)) is disclosed. Miniaturization is achieved through symmetric inductive loading of an electrically small slot section. It is fabricated on a low-loss fused silica wafer through a back-etch of a 5000-angstrom golden metal film, which is 31.5% of the skin depth at 2.45 GHz. The measured bandwidth is 106 MHz and the measured gain is -15 dBi. The theoretical Wheeler-Chu-McLean limit for the gain of a lambda(0)/35 x lambda(0)/35 electrically small antenna with a similar Q factor is -9.6 dBi.
