Classification: CPC H | IPC H

Claim 0:
1. A portable communication device, comprising:
an antenna module supporting a mmWave frequency band and comprising:
a first printed circuit board (PCB), and
a first antenna element disposed on the first PCB and a second antenna element disposed on the first PCB, wherein the first antenna element and the second antenna element form an antenna array to transmit and/or receive a signal of the mmWave frequency band,

a second PCB;
a plurality of power amplifiers (PAs) electrically connected to the antenna array and disposed on the second PCB;
a plurality of low noise amplifiers (LNAs) electrically connected to the antenna array and disposed on the second PCB, wherein a number of the plurality of LNAs electrically connected to the antenna array is greater than a number of the plurality of PAs electrically connected to the antenna array;
a mixer disposed on the second PCB;
a first transmission-reception circuit disposed on the second PCB and electrically connected to the first antenna element, wherein the first transmission-reception circuit includes a first PA among the plurality of PAs and a first LNA among the plurality of LNAs, wherein the first PA forms a portion of a transmission path electrically connected with the mixer and the first antenna element, and wherein the first LNA forms a portion of a first reception path electrically connected with the mixer and the first antenna element; and
a first reception circuit disposed on the second PCB and electrically connected to the second antenna element, wherein the first reception circuit does not include a PA, and includes a second LNA among the plurality of LNAs, and wherein the second LNA forms a portion of a second reception path electrically connected with the mixer and the second antenna element,
wherein the mixer is electrically connected to the first antenna element via the first transmission-reception circuit and the second antenna element via the first reception circuit such that the mixer receives radio frequency (RF) signals from both the first antenna element and the second antenna element.
