            Abstract : 
A novel compact millimetre-wave 32-way ring-cavity power dividing/combining circuit is presented. The ring-cavity power dividing function and the symmetric electromagnetic-field excitation is investigated. A U-band 32-way ring-cavity passive power combiner is developed with reasonable agreement between the simulated and measured results.
