**1.5 Applications of wearable microstrip antenna**

The development of antenna technology for human and machine interface has made qualitative leaps in the use of textiles as antenna substrates [19]. In future, this will permit freedom to design antenna systems worn by the body and integrated into it so; these are called "smart clothes" [20]. They will emerge in various as shown in **Figure 2** [21]:
