“…using PIN diodes increase insertion loss as well as responsible to decrease the positive gain of an antenna for high biasing resistance of PIN diodes [10]. In [13], [14], by varying capacitance of varactor diodes, smooth frequency agility is achieved, but they are non-linearly dependent on applied voltage possessing limited tuning range capability [15]. Besides this, random forest (RF) micro-electro-mechanical system (MEMS) are integrated within the antenna for public safety bands [16], [17] and field-effect transistor (FET) switches are also used as switches presented in [18].…”

In this article, a frequency reconfigurable honey-bee compact microstrip monopole antenna is proposed which is fed by a microstrip line (50 Ω) having the capability of providing dual-band as well as triple-band operation in eight distinct modes. By embedding three PIN diodes overs the honey bee arms, the effective current distribution is controlled hence resonant frequency is also changed in eight distinct modes in real-time. This is the reason the proposed antenna is portrayed as a frequency reconfigurable antenna in this paper which is suitable for cognitive radio application. This proposed antenna can be used for various wireless application such as Bluetooth, Wi-Fi, worldwide interoperability for microwave access (WiMAX), wireless local area network (WLAN), C-band, and X-band applications. The proposed antenna possesses a planner geometry of 39×34×0.87 mm3 which is printed on a substrate as flexible FR-4 (lossy) (εr=4.4 and tanδ=0.019). The proposed antenna exhibits voltage standing wave ratio (VSWR)<2 for all 19 resonant frequencies of interest and perceptible radiation pattern over entire frequency bands with a positive gain. CST microwave studio is used to find out all simulated results of antenna parameters.
