Abstract

A compact arrow shaped microstrip antenna with a rectangular slot is proposed. By embedding a rectangular slot in the patch an additional resonance frequency having opposite polarization compared to the TM₁₀ mode is generated This new frequency is much lower than the TM₀₁ mode frequency of the patch without a slot. The ratio between the two resonant frequencies can be tuned in a wide range by changing the slot length. These two orthogonal modes can also be combined to achieve circularly polarized radiation. The antenna offers an area reduction ∼75% compared to a rectangular patch antenna designed for the same frequency.
