Claim 9:
10. A multichip system, comprising:
a plurality of processor chips each having at least one processor core;
a plurality of antenna module for establishing interchip wireless communication, each of the antenna modules being disposed on one of the processor chips, the antenna module including:
an array of n circular patch antenna elements for 360° end-fire scanning, where n is equal to 4 or a multiple thereof;
a Butler matrix having n/4 submatrices, each of the submatrices including:
two input 90° hybrids each having two outputs and two inputs for selectively receiving signals from a transceiver; and
two output 90° hybrids each having two outputs and two inputs, the two inputs of each output 90° hybrid being coupled to an output of different ones of the input 90° hybrids, each output of the output 90° hybrids being coupled to a different one of the circular patch antenna elements.
