A switchable multi-sector antenna for indoor wireless localarea network (LAN) systems in the 60-GHz band has been proposed. The antenna has a pyramidal configuration. Each isosceles-triangular surface of the pyramid has been inclined 30° from the vertical axis in order to cover an appropriate elevation angle range. This antenna excites a right-handed circularly polarized wave to suppress unwanted multipath delayed waves. The low-loss curved microstrip-line feeding has been introduced at the junction between antenna feed lines and monolithic microwave integrated circuit (MMIC) amplifiers at the bottoms of the pyramid. Using this antenna, the terminal receiver for indoor wireless LAN systems in the 60-GHz band has been developed. Index Terms-Curved microstrip lines, millimeter-wave LAN's, multisector antenna, patch antennas.
