In this paper, diode loaded slot -patch antenna is presented and the effects on the bandwidth (BW) and efficiency are investigated. A single diode-loaded slot patch antenna gives 2.4 GHz frequency operation with broadband radiation. In this study, the design consists of a rectangular microstrip antenna with a parallel slot loaded close to the radiating edge of the patch and three meandering narrow slits embedded on the antenna surface. Two antenna layouts are designed, for different coverage areas: a reference antenna having 4.95 dBi directivity and a diode loaded antenna with 5.36 dBi directivity. A slot-patch operating at 2.4 GHz having 1.2% BW has been utilized as a reference antenna. The slot-patch antenna has been designed using CST microwave studio and implemented. The proposed slot-patch radiation pattern is better than without diode loading radiation pattern. In addition, it has been shown that diode compensation significantly improves the matching level. Theoretical, simulation, and measurement results are in a good agreement. Slot-patch antenna design can be used for RF receiver-transmitter systems..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
