Abstract
An antenna system (308, 309, 310, 312, 314, 316, and 317) for a wrist carried selective call receiver (300) comprises at least first (312 and 314) and second (310) elements, coupled to each other and coupled to the selective call receiver to form a first single magnetic loop antenna (312, 308, 316, and 310) having a first physical orientation. At least one of the first and second elements comprises at least one second single magnetic loop antenna (312, 308, 316, 310, 317, 309, and 314) also coupled to the selective call receiver. The second single magnetic loop antenna has a second physical orientation different from the first physical orientation.
