A miniature platform tolerant antenna is presented which is suitable for low frequency applications. A Split Ring Resonator (SRR) antenna loaded with lumped capacitances is proposed, and the antenna is compact, low proflle and easy to fabricate. It has a maximum dimension of ‚/9 and i10dB bandwidth of 1%. Miniaturized artiflcial magnetic conductor surfaces (AMCs) are designed using capacitance loaded metal patches with individual elements measuring just ‚=70. Placing the SRR above the AMC improves the bandwidth to between 1.5 and 3.5% dependent on the overall size of the AMC and produces a platform tolerant antenna measuring 0.11‚£0:17‚£0:019‚. The performance of the antenna over an AMC with and without vias is studied and discussed. The AMC mounted antenna performances in free space and over a ground plane are also compared.
