VHF antenna has many types, and used in many cases are 1/2λ type. (In particular Yagi antenna is famous.) But this time, we were fabricated antennas of 1λ type and 2λ type. The reasons are theoretical analysis of 1λ type and 2λ type antenna is difficult, and these type explanation papers are not many. So we dared experimental analysis these type antennas, and evaluated performance. This paper reports the performance evaluation of 1λ type and 2λ type antennas for uses to near field communication in an emergency.
