A Design Rule for Inset-fed Rectangular Microstrip Patch Antenna... The inset-fed microstrip antenna provides a method of impedance control with a planar feed configuration [1-2]. The experimental and numerical results showed that the input impedance of an inset-fed rectangular patch varied as a Cos4 function of the normalized inset depth [1]. Resonant Antenna - an overview | ScienceDirect Topics In Fig. 6.10, RF MEMS switches are used to tune the frequency of a slot antenna (Van Caekenberghe and Sarabandi, 2008). When the switches change to ON-state, the slot length is reduced and the resonant frequency increases. In Fig. 6.11, RF MEMS switches are used to tune the resonance frequency of a fractal antenna (Kingsley et al., 2007). It can be observed that the sequential activation of the RF MEMS switches shifts the antenna resonance to lower frequencies.

respectively. By using the strip and slot, the proposed antenna deals properly with frequency shift for real application when embedded inside a handheld reader. V. CONCLUSION Thus the slot microstrip antenna was designed.The antenna shows good performance at 2.4GHz. Antenna gain, directivity, efficiency and return loss are measured.
