Compact bow shape microstrip patch antenna with different substrates

Microstrip patch antenna has small size, low cost, easy in construction and provides high performance over wide band of frequencies. Here, a new approach for designing a very small size bow shaped microstrip patch antenna has been proposed. The proposed bow shape microstrip patch antenna having Benzocyclobutene as a substrate has good resonant frequency (4.35 GHz).Also, the size is reduced more than 40% as compared to rectangular patch microstrip antenna for TM₁₀ mode and resonant frequency of 4.35 GHz having Benzocyclobutene as substrate. The Bow shape microstrip patch antenna having substrate Benzocyclobutene also shows the good results for return loss and radiation pattern.
