When a microstrip patch antenna is brought closer than 0.2λ to an identical patch the resonant frequency of that antenna changes from the designed frequency. In this paper numerical results for the resonant frequency are presented from a theoretical analysis of the mutually coupled H-plane microstrip patch antennas with confirming experimental results. We have also established the relation between resonant frequency of E-plane coupled and H-plane coupled microstrip patch antennas. 1. SYMBOLS a = Width of the patch b = Length of the patch h = Thickness of the substrate er = Relative dielectric constant eeff = Effective dielectric constant λ = Free space wavelength d = Spacing between the edges of coupled patches fdesign = Design frequency fr−E = Resonant frequency of the E-plane coupled microstrip patch antenna fr−H = Resonant frequency of the H-plane coupled microstrip patch antenna
